>gnl|CDD|189000 cd08662, M13, Peptidase family M13 includes neprilysin,
           endothelin-converting enzyme I.  M13 family of
           metallopeptidases includes neprilysin (neutral
           endopeptidase, NEP, enkephalinase, CD10, CALLA, EC
           3.4.24.11), endothelin-converting enzyme I (ECE-1, EC
           3.4.24.71), erythrocyte surface antigen KELL (ECE-3),
           phosphate-regulating gene on the X chromosome (PHEX),
           soluble secreted endopeptidase (SEP), and damage-induced
           neuronal endopeptidase (DINE)/X-converting enzyme (XCE).
           These proteins consist of a short N-terminal cytoplasmic
           domain, a single transmembrane helix, and a larger
           C-terminal extracellular domain containing the active
           site. Proteins in this family fulfill a broad range of
           physiological roles due to the greater variation in the
           S2' subsite allowing substrate specificity. NEP is
           expressed in a variety of tissues including kidney and
           brain, and is involved in many physiological and
           pathological processes, including blood pressure and
           inflammatory response. It degrades a wide array of
           substrates such as substance P, enkephalins,
           cholecystokinin, neurotensin and somatostatin.  It is an
           important enzyme in the regulation of amyloid-beta
           (Abeta) protein that forms amyloid plaques that are
           associated with Alzeimers disease (AD). ECE-1 catalyzes
           the final rate-limiting step in the biosynthesis of
           endothelins via post-translational conversion of the
           biologically inactive big endothelins. Like NEP, it also
           hydrolyses bradykinin, substance P, neurotensin and
           Abeta.  Endothelin-1 overproduction has been implicated
           in various diseases, including stroke, asthma,
           hypertension, and cardiac and renal failure. Kell is a
           homolog of NEP and constitutes a major antigen on human
           erythrocytes; it preferentially cleaves big endothelin-3
           to produce bioactive endothelin-3, but is also known to
           cleave substance P and neurokinin A. PHEX forms a
           complex interaction with fibroblast growth factor 23
           (FGF23) and matrix extracellular phosphoglycoprotein,
           causing bone mineralization. A loss-of-function mutation
           in PHEX disrupts this interaction leading to
           hypophosphatemic rickets; X-linked hypophosphatemic
           (XLH) rickets is the most common form of metabolic
           rickets. ECEL1 is a brain metalloprotease involved in
           the critical role in the nervous regulation of the
           respiratory system, while DINE (damage induced neuronal
           endopeptidase) is abundantly expressed in the
           hypothalamus and its expression responds to nerve injury
           as well. Thus, majority of these M13 proteases are prime
           therapeutic targets for selective inhibition.

>gnl|CDD|216499 pfam01431, Peptidase_M13, Peptidase family M13.  Mammalian enzymes
           are typically type-II membrane anchored enzymes which
           are known, or believed to activate or inactivate
           oligopeptide (pro)-hormones such as opioid peptides. The
           family also contains a bacterial member believed to be
           involved with milk protein cleavage.

>gnl|CDD|198205 cd10342, SH2_SAP1, Src homology 2 (SH2) domain found in
          SLAM-associated protein (SAP)1.  The X-linked
          lymphoproliferative syndrome (XLP) gene encodes SAP
          (also called SH2D1A/DSHP) a protein that consists of a
          5 residue N-terminus, a single SH2 domain, and a short
          25 residue C-terminal tail.  XLP is characterized by an
          extreme sensitivity to Epstein-Barr virus.  Both T and
          natural killer (NK) cell dysfunctions have been seen in
          XLP patients. SAP binds the cytoplasmic tail of
          Signaling lymphocytic activation molecule (SLAM), 2B4,
          Ly-9, and CD84. SAP is believed to function as a
          signaling inhibitor, by blocking or regulating binding
          of other signaling proteins. SAP and the SAP-like
          protein EAT-2 recognize the sequence motif TIpYXX[VI],
          which is found in the cytoplasmic domains of a
          restricted number of T, B, and NK cell surface
          receptors and are proposed to be natural inhibitors or
          regulators of the physiological role of a small family
          of receptors on the surface of these cells.  In general
          SH2 domains are involved in signal transduction. They
          typically bind pTyr-containing ligands via two surface
          pockets, a pTyr and hydrophobic binding pocket,
          allowing proteins with SH2 domains to localize to
          tyrosine phosphorylated sites.
