>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.
