CC -!- FUNCTION: Non-receptor tyrosine-protein kinase that plays a role in
CC many biological processes including regulation of cell growth and
CC survival, cell adhesion, integrin-mediated signaling, cytoskeletal
CC remodeling, cell motility, immune response and axon guidance. Inactive
CC FYN is phosphorylated on its C-terminal tail within the catalytic
CC domain. Following activation by PKA, the protein subsequently
CC associates with PTK2/FAK1, allowing PTK2/FAK1 phosphorylation,
CC activation and targeting to focal adhesions. Involved in the regulation
CC of cell adhesion and motility through phosphorylation of CTNNB1 (beta-
CC catenin) and CTNND1 (delta-catenin). Regulates cytoskeletal remodeling
CC by phosphorylating several proteins including the actin regulator WAS
CC and the microtubule-associated proteins MAP2 and MAPT. Promotes cell
CC survival by phosphorylating AGAP2/PIKE-A and preventing its apoptotic
CC cleavage. Participates in signal transduction pathways that regulate
CC the integrity of the glomerular slit diaphragm (an essential part of
CC the glomerular filter of the kidney) by phosphorylating several slit
CC diaphragm components including NPHS1, KIRREL1 and TRPC6. Plays a role
CC in neural processes by phosphorylating DPYSL2, a multifunctional
CC adapter protein within the central nervous system, ARHGAP32, a
CC regulator for Rho family GTPases implicated in various neural
CC functions, and SNCA, a small pre-synaptic protein. Participates in the
CC downstream signaling pathways that lead to T-cell differentiation and
CC proliferation following T-cell receptor (TCR) stimulation.
CC Phosphorylates PTK2B/PYK2 in response to T-cell receptor activation.
CC Also participates in negative feedback regulation of TCR signaling
CC through phosphorylation of PAG1, thereby promoting interaction between
CC PAG1 and CSK and recruitment of CSK to lipid rafts. CSK maintains LCK
CC and FYN in an inactive form. Promotes CD28-induced phosphorylation of
CC VAV1. In mast cells, phosphorylates CLNK after activation of
CC immunoglobulin epsilon receptor signaling (By similarity).
