The Src family of tyrosine kinases include nine members in vertebrates, including c-Src, Yes, Fgr, Yrk, Fyn, Lyn, Hck, Lck, and Blk. Src-family kinases transduce signals that are involved in the control of a variety of cellular processes, including proliferation, differentiation, motility, and adhesion. Fyn is a 59 kDa member of the Src family of tyrosine kinases that conatins a conserved carboxy terminus and unique N-terminal region. Fyn is N-myristoylated and targeted to the plasma membrane, where it is palmitoylated. Phosphorylation regulates the activity of Fyn at conserved residues, Tyr-420 and Tyr-531. Fyn clusters in caveolae-like membrane microdomains and can interact with a variety of other signaling molecules. Fyn activity is important during T cell receptor signaling, neuronal synaptic transmission, and adhesion-mediated signaling.

Western blot analysis of adult mouse brain tissue lysate. The blot was probed with mouse monoclonal anti-Fyn (N-terminal region) at 1:125 (lane 1) and 1:500 (lane 2).

Clone M238 was generated from a recombinant human Fyn protein that included amino acids in the N-terminal region. This sequence is highly conserved in rat and mouse Fyn.
