>gnl|CDD|211386 cd11300, Fut8_like, Alpha 1-6-fucosyltransferase. Alpha
1,6-fucosyltransferase (Fut8) transfers a fucose moiety
from GDP-fucose to the reducing terminal
N-acetylglucosamine of the core structure of Asn-linked
oligosaccharides, in a process termed core fucosylation.
Core fucosylation is essential for the function of
growth factor receptors. O-fucosyltransferase-like
proteins are GDP-fucose dependent enzymes with
similarities to the family 1 glycosyltransferases (GT1).
They are soluble ER proteins that may be proteolytically
cleaved from a membrane-associated preprotein, and are
involved in the O-fucosylation of protein substrates,
the core fucosylation of growth factor receptors, and
other processes.

>gnl|CDD|212726 cd11792, SH3_Fut8, Src homology 3 domain of
Alpha1,6-fucosyltransferase (Fut8). Fut8 catalyzes the
alpha1,6-linkage of a fucose residue from a donor
substrate to N-linked oligosaccharides on glycoproteins
in a process called core fucosylation, which is crucial
for growth factor receptor-mediated biological
functions. Fut8-deficient mice show severe growth
retardation, early death, and a pulmonary emphysema-like
phenotype. Fut8 is also implicated to play roles in
aging and cancer metastasis. It contains an N-terminal
coiled-coil domain, a catalytic domain, and a C-terminal
SH3 domain. The SH3 domain of Fut8 is located in the
lumen and its role in glycosyl transfer is unclear. SH3
domains are protein interaction domains that bind to
proline-rich ligands with moderate affinity and
selectivity, preferentially to PxxP motifs. They play
versatile and diverse roles in the cell including the
regulation of enzymes, changing the subcellular
localization of signaling pathway components, and
mediating the formation of multiprotein complex
assemblies.

Bradyrhizobium NodZ. Bradyrhizobium NodZ is an alpha
1,6-fucosyltransferase involved in the biosynthesis of
the nodulation factor, a lipo-chitooligosaccharide
formed by three-to-six beta-1,4-linked
N-acetyl-d-glucosamine (GlcNAc) residues and a fatty
acid acyl group attached to the nitrogen atom at the
non-reducing end. NodZ transfers L-fucose from the
GDP-beta-L-fucose donor to the reducing residue of the
chitin oligosaccharide backbone, before the attachment
of a fatty acid group. O-fucosyltransferase-like

proteins 1 and 2, and similar domains. JNK-interacting
proteins (JIPs) function as scaffolding proteins for
c-Jun N-terminal kinase (JNK) signaling pathways. They
bind to components of Mitogen-activated protein kinase
(MAPK) pathways such as JNK, MKK, and several MAP3Ks
such as MLK and DLK. There are four JIPs (JIP1-4); all
contain a JNK binding domain. JIP1 and JIP2 also contain
SH3 and Phosphotyrosine-binding (PTB) domains. Both are
highly expressed in the brain and pancreatic beta-cells.
JIP1 functions as an adaptor linking motor to cargo
during axonal transport and also is involved in
regulating insulin secretion. JIP2 form complexes with
fibroblast growth factor homologous factors (FHFs),
which facilitates activation of the p38delta MAPK. The
SH3 domain of JIP1 homodimerizes at the interface
usually involved in proline-rich ligand recognition,
despite the lack of this motif in the domain itself. SH3

of Vinexin, also called Sorbin and SH3 domain containing
3 (Sorbs3). Vinexin is also called Sorbs3, SH3P3, and
SH3-containing adapter molecule 1 (SCAM-1). It is an
adaptor protein containing one sorbin homology (SoHo)
and three SH3 domains. Vinexin was first identified as a
vinculin binding protein; it is co-localized with

are several splice variants of vinexin: alpha, which
contains the SoHo and three SH3 domains and displays
tissue-specific expression; and beta, which contains
only the three SH3 domains and is widely expressed.
Vinexin alpha stimulates the accumulation of F-actin at
focal contact sites. Vinexin also promotes keratinocyte
migration and wound healing. The SH3 domains of vinexin
have been reported to bind a number of ligands including

>gnl|CDD|211387 cd11301, Fut1_Fut2_like, Alpha-1,2-fucosyltransferase.
Alpha-1,2-fucosyltransferases (Fut1, Fut2) catalyze the
transfer of alpha-L-fucose to the terminal
beta-D-galactose residue of glycoconjugates via an
alpha-1,2-linkage, generating carbohydrate structures
that exhibit H-antigenicity for blood-group
carbohydrates. These structures also act as ligands for
morphogenesis, the adhesion of microbes, and
metastasizing cancer cells. Fut1 is responsible for
producing the H antigen on red blood cells. Fut2 is
expressed in epithelia of secretory tissues, and
individuals termed "secretors" have at least one
functional copy of the gene; they secrete H antigen
which is further processed into A and/or B antigens
depending on the ABO genotype. O-fucosyltransferase-like
proteins are GDP-fucose dependent enzymes with
similarities to the family 1 glycosyltransferases (GT1).
They are soluble ER proteins that may be proteolytically
cleaved from a membrane-associated preprotein, and are
involved in the O-fucosylation of protein substrates,
the core fucosylation of growth factor receptors, and
other processes.

>gnl|CDD|212713 cd11779, SH3_Irsp53_BAIAP2L, Src Homology 3 domain of Insulin
Receptor tyrosine kinase Substrate p53, Brain-specific
Angiogenesis Inhibitor 1-Associated Protein 2
(BAIAP2)-Like proteins, and similar proteins. Proteins
in this family include IRSp53, BAIAP2L1, BAIAP2L2, and
similar proteins. They all contain an
Inverse-Bin/Amphiphysin/Rvs (I-BAR) or IMD domain in
addition to the SH3 domain. IRSp53, also known as
BAIAP2, is a scaffolding protein that takes part in many
signaling pathways including Cdc42-induced filopodia
formation, Rac-mediated lamellipodia extension, and
spine morphogenesis. IRSp53 exists as multiple splicing
variants that differ mainly at the C-termini. BAIAP2L1,
also called IRTKS (Insulin Receptor Tyrosine Kinase
Substrate), serves as a substrate for the insulin
receptor and binds the small GTPase Rac. It plays a role
in regulating the actin cytoskeleton and colocalizes
with F-actin, cortactin, VASP, and vinculin. IRSp53 and
IRTKS also mediate the recruitment of effector proteins
Tir and EspFu, which regulate host cell actin
reorganization, to bacterial attachment sites. BAIAP2L2
co-localizes with clathrin plaques but its function has
not been determined. The SH3 domains of IRSp53 and IRTKS
have been shown to bind the proline-rich C-terminus of
EspFu. SH3 domains are protein interaction domains that
bind to proline-rich ligands with moderate affinity and
selectivity, preferentially to PxxP motifs. They play
versatile and diverse roles in the cell including the
regulation of enzymes, changing the subcellular
localization of signaling pathway components, and
mediating the formation of multiprotein complex
assemblies.
