>gnl|CDD|133201 cd05070, PTKc_Fyn_Yrk, Catalytic domain of the Protein Tyrosine
Kinases, Fyn and Yrk. Protein Tyrosine Kinase (PTK)
family; Fyn and Yrk kinases; catalytic (c) domain. The
PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Fyn and
Yrk are members of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival,
and differentiation. Fyn, together with Lck, plays a
critical role in T-cell signal transduction by
phosphorylating ITAM (immunoreceptor tyr activation
motif) sequences on T-cell receptors, ultimately
leading to the proliferation and differentiation of
T-cells. In addition, Fyn is involved in the
myelination of neurons, and is implicated in
Alzheimer's and Parkinson's diseases. Yrk has been
detected only in chickens. It is primarily found in
neuronal and epithelial cells and in macrophages. It
may play a role in inflammation and in response to
injury.
