20658524	The serine 21 (s21) residue of fyn is a protein kinase a (pka) recognition site within an rxxs motif of the amino terminal sh4 domain of fyn. In addition, s21 is critical for fyn kinase-linked cellular signaling. Mutation of s21a blocks pka phosphorylation of fyn and alters its tyrosine kinase activity.

Active but not kinase-dead fyn interacts with pike-a and phosphorylates it on both y682 and y774 residues. Tyrosine phosphorylation in pike-a is required for its association with active fyn but not for akt. Mutation of d into a in pike-a protects it from caspase cleavage and promotes cell survival.

9425276	PDGF-induced phosphorylation of Tyr28 in the N-terminus of Fyn affects Fyn activation. We show here that Fyn, a member of the Src family, is phosphorylated on Tyr28 in the unique N-terminal part of the molecule after interaction with the intracellular domain of the PDGF beta-receptor. Activated Fyn furthermore undergoes autophosphorylation on Tyr30, Tyr39 and Tyr420. When Fyn mutants with Tyr28, Tyr30 or Tyr39 replaced with phenylalanine residues were transfected into NIH3T3 cells a decreased activation after PDGF stimulation was seen, suggesting a functional importance of the N-terminal tyrosine phosphorylation of Fyn.

11806999	All 3 tyrosines of CD150 (Tyr281, Tyr307, Tyr327) are phosphorylated by the src kinase Fyn. CD150 is unique among its homologues in the immunoglobulin superfamily in that it is able to bind SAP, a floating SH2 domain, in the absence of tyrosine phosphorylation. In this study, using a detailed mutagenesis mapping approach we have shown that SAP binding to CD150 is in fact bimodal. Prior to tyrosine phosphorylation, SAP binds the membrane-proximal motif surrounding Tyr281. Following tyrosine phosphorylation by tyrosine kinases such as Fyn, SAP binds additionally to the distal motif surrounding Tyr327.

23770091	Mutagenesis analysis of ESDN's seven intracellular tyrosines in YxxP motifs found several contribute to the binding of ESDN to the SH2 domains of both CrkCT10 regulator of kinase Crk-Like (CrkL) and a representative SFK Fyn. Quantitative mass spectrometry showed that at least three of these (Y565, Y621 and Y750), as well as non-YxxP Y715, are reversibly phosphorylated. SFK activity was shown to be sufficient, but not required for the interaction between ESDN and the CrkL-SH2 domain. Finally, antibody-mediated ESDN clustering induces ESDN tyrosine phosphorylation and CrkL-SH2 binding.

The Y60F mutant of Hic-5 was not phosphorylated, and Hic-5 phosphorylated on tyrosine 60 was bound specifically to the SH2 domain of Csk. Specific phosphorylation of Hic-5 by CAKbeta and Fyn may activate a signaling pathway mediated by Hic-5.

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