>gnl|CDD|143208 cd05731, Ig3_L1-CAM_like, Third immunoglobulin (Ig)-like domain
          of the L1 cell adhesion molecule (CAM).
          Ig3_L1-CAM_like: domain similar to the third
          immunoglobulin (Ig)-like domain of the L1 cell adhesion
          molecule (CAM). L1 belongs to the L1 subfamily of cell
          adhesion molecules (CAMs) and is comprised of an
          extracellular region having six Ig-like domains and
          five fibronectin type III domains, a transmembrane
          region and an intracellular domain. L1 is primarily
          expressed in the nervous system and is involved in its
          development and function. L1 is associated with an
          X-linked recessive disorder, X-linked hydrocephalus,
          MASA syndrome, or spastic paraplegia type 1, that
          involves abnormalities of axonal growth. This group
          also contains the chicken neuron-glia cell adhesion
          molecule, Ng-CAM and human neurofascin.

>gnl|CDD|143241 cd05764, Ig_2, Subgroup of the immunoglobulin (Ig) superfamily.
          Ig_2: subgroup of the immunoglobulin (Ig) domain found
          in the Ig superfamily. The Ig superfamily is a
          heterogenous group of proteins, built on a common fold
          comprised of a sandwich of two beta sheets. Members of
          the Ig superfamily are components of immunoglobulin,
          neuroglia, cell surface glycoproteins, such as T-cell
          receptors, CD2, CD4, CD8, and membrane glycoproteins,
          such as butyrophilin and chondroitin sulfate
          proteoglycan core protein. A predominant feature of
          most Ig domains is a disulfide bridge connecting the
          two beta-sheets with a tryptophan residue packed
          against the disulfide bond.

>gnl|CDD|143170 cd04969, Ig5_Contactin_like, Fifth Ig domain of contactin.
          Ig5_Contactin_like: Fifth Ig domain of contactins.
          Contactins are neural cell adhesion molecules and are
          comprised of six Ig domains followed by four
          fibronectin type III(FnIII) domains anchored to the
          membrane by glycosylphosphatidylinositol. The first
          four Ig domains form the intermolecular binding
          fragment, which arranges as a compact U-shaped module
          via contacts between Ig domains 1 and 4, and between Ig
          domains 2 and 3. Contactin-2 (TAG-1, axonin-1) may play
          a part in the neuronal processes of neurite outgrowth,
          axon guidance and fasciculation, and neuronal
          migration. This group also includes contactin-1 and
          contactin-5. The different contactins show different
          expression patterns in the central nervous system.
          During development and in adulthood, contactin-2 is
          transiently expressed in subsets of central and
          peripheral neurons. Contactin-5 is expressed
          specifically in the rat postnatal nervous system,
          peaking at about 3 weeks postnatal, and a lack of
          contactin-5 (NB-2) results in an impairment of neuronal
          act ivity in the rat auditory system. Contactin-5 is
          highly expressed in the adult human brain in the
          occipital lobe and in the amygdala. Contactin-1 is
          differentially expressed in tumor tissues and may,
          through a RhoA mechanism, facilitate invasion and
          metastasis of human lung adenocarcinoma.

          proteoglycan perlecan, also known as HSPG2.
          Ig_Perlecan_D2_like: the immunoglobulin (Ig)-like
          domain II (D2) of the human basement membrane heparan
          sulfate proteoglycan perlecan, also known as HSPG2.
          Perlecan consists of five domains. Domain I has three
          putative heparan sulfate attachment sites; domain II
          has four LDL receptor-like repeats, and one Ig-like
          repeat; domain III resembles the short arm of laminin
          chains; domain IV has multiple Ig-like repeats (21
          repeats in human perlecan); and domain V resembles the
          globular G domain of the laminin A chain and internal
          repeats of EGF. Perlecan may participate in a variety
          of biological functions including cell binding,
          LDL-metabolism, basement membrane assembly and
          selective permeability, calcium binding, and growth-
          and neurite-promoting activities.

>gnl|CDD|143202 cd05725, Ig3_Robo, Third immunoglobulin (Ig)-like domain in Robo
          (roundabout) receptors.  Ig3_Robo: domain similar to
          the third immunoglobulin (Ig)-like domain in Robo
          (roundabout) receptors. Robo receptors play a role in
          the development of the central nervous system (CNS),
          and are receptors of Slit protein. Slit is a repellant
          secreted by the neural cells in the midline. Slit acts
          through Robo to prevent most neurons from crossing the
          midline from either side. Three mammalian Robo homologs
          (robo1, -2, and -3), and three mammalian Slit homologs
          (Slit-1,-2, -3), have been identified. Commissural
          axons, which cross the midline, express low levels of
          Robo; longitudinal axons, which avoid the midline,
          express high levels of Robo. robo1, -2, and -3 are
          expressed by commissural neurons in the vertebrate
          spinal cord and Slits 1, -2, -3 are expressed at the
          ventral midline. Robo-3 is a divergent member of the
          Robo family which instead of being a positive regulator
          of slit responsiveness, antagonizes slit responsiveness
          in precrossing axons.  The Slit-Robo interaction is
          mediated by the second leucine-rich repeat (LRR) domain
          of Slit and the two N-terminal Ig domains of Robo, Ig1
          and Ig2. The primary Robo binding site for Slit2 has
          been shown by surface plasmon resonance experiments and
          mutational analysis to be is the Ig1 domain, while the
          Ig2 domain has been proposed to harbor a weak secondary
          binding site.

          regulation. Included in this group is the tumor
          suppressor protein DCC, which is deleted in colorectal
          carcinoma . DCC and neogenin each have four Ig-like

          fibroblast growth factor (FGF) receptor and similar
          proteins.  Ig2_FGFR_like: domain similar to the second
          immunoglobulin (Ig)-like domain of fibroblast growth
          factor (FGF) receptor. FGF receptors bind FGF signaling
          polypeptides. FGFs participate in multiple processes
          such as morphogenesis, development, and angiogenesis.
          FGFs bind to four FGF receptor tyrosine kinases (FGFR1,
          -2, -3, -4). Receptor diversity is controlled by
          alternative splicing producing splice variants with
          different ligand binding characteristics and different
          expression patterns. FGFRs have an extracellular region
          comprised of three Ig-like domains, a single
          transmembrane helix, and an intracellular tyrosine
          kinase domain. Ligand binding and specificity reside in
          the Ig-like domains 2 and 3, and the linker region that
          connects these two. FGFR activation and signaling
          depend on FGF-induced dimerization, a process involving
          cell surface heparin or heparin sulfate proteoglycans.
          This group also contains fibroblast growth factor (FGF)
          receptor_like-1(FGFRL1). FGFRL1 does not have a protein
          tyrosine kinase domain at its C terminus; neither does
          its cytoplasmic domain appear to interact with a
          signaling partner. It has been suggested that FGFRL1
          may not have any direct signaling function, but instead
          acts as a decoy receptor trapping FGFs and preventing
          them from binding other receptors.

          of peroxidasin.  Ig3_Peroxidasin: the third

          Peroxidasin has a peroxidase domain and interacting
          extracellular motifs containing four Ig-like domains.
          It has been suggested that peroxidasin is secreted and
          has functions related to the stabilization of the
          extracellular matrix. It may play a part in various
          other important processes such as removal and
          destruction of cells which have undergone programmed
          cell death, and protection of the organism against
          non-self.

          (roundabout) receptors.  Ig2_Robo: domain similar to
          the second immunoglobulin (Ig)-like domain in Robo
          (roundabout) receptors. Robo receptors play a role in
          the development of the central nervous system (CNS),
          and are receptors of Slit protein. Slit is a repellant
          secreted by the neural cells in the midline. Slit acts
          through Robo to prevent most neurons from crossing the
          midline from either side. Three mammalian Robo homologs
          (robo1, -2, and -3), and three mammalian Slit homologs
          (Slit-1,-2, -3), have been identified. Commissural
          axons, which cross the midline, express low levels of
          Robo; longitudinal axons, which avoid the midline,
          express high levels of Robo. robo1, -2, and -3 are
          expressed by commissural neurons in the vertebrate
          spinal cord and Slits 1, -2, -3 are expressed at the
          ventral midline. Robo-3 is a divergent member of the
          Robo family which instead of being a positive regulator
          of slit responsiveness, antagonizes slit responsiveness
          in precrossing axons.  The Slit-Robo interaction is
          mediated by the second leucine-rich repeat (LRR) domain
          of Slit and the two N-terminal Ig domains of Robo, Ig1
          and Ig2. The primary Robo binding site for Slit2 has
          been shown by surface plasmon resonance experiments and
          mutational analysis to be is the Ig1 domain, while the
          Ig2 domain has been proposed to harbor a weak secondary
          binding site.

          first immunoglobulin (Ig) domain of poliovirus receptor
          (PVR, also known as CD155). Poliovirus (PV) binds to
          its cellular receptor (PVR/CD155) to initiate
          infection. CD155 is a membrane-anchored, single-span
          glycoprotein; its extracellular region has three
          Ig-like domains. There are four different isotypes of
          CD155 (referred to as alpha, beta, gamma, and delta),
          that result from alternate splicing of the CD155 mRNA,
          and have identical extracellular domains. CD155-beta
          and - gamma, are secreted, CD155-alpha and delta are
          membrane-bound and function as PV receptors. The virus
          recognition site is contained in the amino-terminal
          domain, D1. Having the virus attachment site on the
          receptor distal from the plasma membrane, may be
          important for successful initiation of infection of
          cells by the virus. CD155 binds in the poliovirus
          "canyon" with a footprint similar to that of the
          intercellular adhesion molecule-1 receptor on human
          rhinoviruses. This group also includes the first

          Contactins are neural cell adhesion molecules and are
          comprised of six Ig domains followed by four
          fibronectin type III(FnIII) domains anchored to the
          membrane by glycosylphosphatidylinositol. The first
          four Ig domains form the intermolecular binding
          fragment, which arranges as a compact U-shaped module
          via contacts between Ig domains 1 and 4, and between Ig
          domains 2 and 3. Contactin-2 (TAG-1, axonin-1) may play
          a part in the neuronal processes of neurite outgrowth,
          axon guidance and fasciculation, and neuronal
          migration. This group also includes contactin-1 and
          contactin-5. The different contactins show different
          expression patterns in the central nervous system.
          During development and in adulthood, contactin-2 is
          transiently expressed in subsets of central and
          peripheral neurons. Contactin-5 is expressed
          specifically in the rat postnatal nervous system,

          contactin-5 (NB-2) results in an impairment of neuronal
          act ivity in the rat auditory system. Contactin-5 is
          highly expressed in the adult human brain in the

          three members, VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1) and
          VEGFR-3 (Flt-4). VEGF-A interacts with both VEGFR-1 and
          VEGFR-2. VEGFR-1 binds strongest to VEGF, VEGF-2 binds
          more weakly. VEGFR-3 appears not to bind VEGF, but
          binds other members of the VEGF family (VEGF-C and -D).
          VEGFRs bind VEGFs with high affinity with the IG-like
          domains. VEGF-A is important to the growth and
          maintenance of vascular endothelial cells and to the
          development of new blood- and lymphatic-vessels in
          physiological and pathological states. VEGFR-2 is a
          major mediator of the mitogenic, angiogenic and

          VEGFR-1 may play an inhibitory part in these processes
          by binding VEGF and interfering with its interaction
          with VEGFR-2. VEGFR-1 has a signaling role in mediating
          monocyte chemotaxis. VEGFR-2 and -1 may mediate a

          of Neural Cell Adhesion Molecule NCAM-1 (NCAM).
          Ig3_NCAM-1_like: domain similar to the third
          immunoglobulin (Ig)-like domain of Neural Cell Adhesion
          Molecule NCAM-1 (NCAM). NCAM plays important roles in
          the development and regeneration of the central nervous
          system, in synaptogenesis and neural migration. NCAM
          mediates cell-cell and cell-substratum recognition and
          adhesion via homophilic (NCAM-NCAM), and heterophilic
          (NCAM-non-NCAM), interactions. NCAM is expressed as
          three major isoforms having different intracellular
          extensions. The extracellular portion of NCAM has five
          N-terminal Ig-like domains and two fibronectin type III
          domains. The double zipper adhesion complex model for
          NCAM homophilic binding involves Ig1, Ig2, and Ig3. By
          this model, Ig1,and Ig2 mediate dimerization of NCAM
          molecules situated on the same cell surface (cis
          interactions), and Ig3 domains mediate interactions
          between NCAM molecules expressed on the surface of
          opposing cells (trans interactions), through binding to
          the Ig1 and Ig2 domains. The adhesive ability of NCAM
          is modulated by the addition of polysialic acid chains
          to the fifth Ig-like domain.

          Ig_CEACAM_D1_like : immunoglobulin (IG)-like domain 1
          in carcinoembryonic antigen (CEA) related cell adhesion
          molecule (CEACAM) protein subfamily-like. The CEA
          family is a group of anchored or secreted
          glycoproteins, expressed by epithelial cells,
          leukocytes, endothelial cells and placenta. The CEA
          family is divided into the CEACAM and
          pregnancy-specific glycoprotein (PSG) subfamilies. This
          group represents the CEACAM subfamily. CEACAM1 has many
          important cellular functions, it is a cell adhesion
          molecule, and a signaling molecule that regulates the
          growth of tumor cells, it is an angiogenic factor, and
          is a receptor for bacterial and viral pathogens,
          including mouse hepatitis virus (MHV). In mice, four
          isoforms of CEACAM1 generated by alternative splicing
          have either two [D1, D4] or four [D1-D4] Ig-like
          domains on the cell surface. This family corresponds to
          the D1 Ig-like domain. Also belonging to this group is
          the N-terminal immunoglobulin (Ig)-like domain of the
          signaling lymphocyte activation molecule (SLAM) family,
          CD84-like family. The SLAM family is a group of
          immune-cell specific receptors that can regulate both
          adaptive and innate immune responses. SLAM family
          proteins are organized as an extracellular domain with
          having two or four Ig-like domains, a single
          transmembrane segment, and a cytoplasmic region having
          tyr-based motifs. The extracellular domain is organized
          as a membrane-distal Ig variable (IgV) domain that is
          responsible for ligand recognition and a
          membrane-proximal truncated Ig constant-2 (IgC2)
          domain.

          Ig1_Contactin-2: First Ig domain of the neural cell
          adhesion molecule contactin-2-like. Contactins are
          comprised of six Ig domains followed by four
          fibronectin type III (FnIII) domains anchored to the
          membrane by glycosylphosphatidylinositol. Contactin-2
          (TAG-1, axonin-1) facilitates cell adhesion by
          homophilic binding between molecules in apposed
          membranes. It may play a part in the neuronal processes
          of neurite outgrowth, axon guidance and fasciculation,
          and neuronal migration. The first four Ig domains form
          the intermolecular binding fragment, which arranges as
          a compact U-shaped module by contacts between IG
          domains 1 and 4, and domains 2 and 3. The different
          contactins show different expression patterns in the
          central nervous system. During development and in
          adulthood, contactin-2 is transiently expressed in
          subsets of central and peripheral neurons. Contactin-2
          is also expressed in retinal amacrine cells in the
