>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.

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

highly expressed in the brain and pancreatic beta-cells.
JIP1 functions as an adaptor linking motor to cargo

and three SH3 domains. Vinexin was first identified as a
vinculin binding protein; it is co-localized with
vinculin at cell-ECM and cell-cell adhesion sites. There
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
vinculin, WAVE2, DLG5, Abl, and Cbl. 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.

(SH3) domains are protein interaction domains that bind
proline-rich ligands with moderate affinity and
selectivity, preferentially to PxxP motifs. Thus, they
are referred to as proline-recognition domains (PRDs).
SH3 domains are less selective and show more diverse
specificity compared to other PRDs. They have been shown
to bind peptide sequences that lack the PxxP motif;
examples include the PxxDY motif of Eps8 and the
RKxxYxxY sequence in SKAP55. SH3 domain containing
proteins 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

superfamily are adaptor proteins that associate with a
number of protein partners, facilitating complex
formation and signal transduction.

containing proteins 1, 3, and 4 (FRMPD1, 3, 4) FERM
domain C-lobe. The function of FRMPD1, FRMPD3, and
FRMPD4 is unknown at present. These proteins contain an
N-terminal PDZ (post synaptic density protein (PSD95),
Drosophila disc large tumor suppressor (Dlg1), and
zonula occludens-1 protein (zo-1) domain and a
C-terminal FERM domain. PDZ (also known as DHR (Dlg
homologous region) or GLGF
(glycine-leucine-glycine-phenylalanine) domains) help
anchor transmembrane proteins to the cytoskeleton and
hold together signaling complexes. PDZ domains bind to a
short region of the C-terminus of other specific
proteins. The FERM domain is composed of three
subdomains (FERM_N, FERM_M, FERM_C/N, alpha-, and
C-lobe/A-lobe, B-lobe, C-lobe/F1, F2, F3) which form a
clover leaf fold. The C-lobe/F3 within the FERM domain
is part of the PH domain family. The FERM domain is
found in the cytoskeletal-associated proteins such as
ezrin, moesin, radixin, 4.1R, and merlin. These proteins
provide a link between the membrane and cytoskeleton and
are involved in signal transduction pathways. The FERM
domain is also found in protein tyrosine phosphatases
(PTPs) , the tyrosine kinases FAK and JAK, in addition
to other proteins involved in signaling. This domain is
structurally similar to the PH and PTB domains and
consequently is capable of binding to both peptides and
phospholipids at different sites.

carry scaffolding functions through multiple sites of

including ankyrin (ANK) repeats, a long proline rich
region, as well as SH3, PDZ, and SAM domains. They bind
a variety of membrane and cytosolic proteins, and exist
in alternatively spliced isoforms. They are highly
enriched in postsynaptic density (PSD) where they
interact with the cytoskeleton and with postsynaptic
membrane receptors including NMDA and glutamate
receptors. They are crucial in the construction and
organization of the PSD and dendritic spines of
excitatory synapses. There are three members of this
family (Shank1, Shank2, Shank3) which show distinct and
