UniProtKB - P13406 (FYN_XENLA)
Protein
Tyrosine-protein kinase Fyn
Gene
fyn
Organism
Xenopus laevis (African clawed frog)
Status
Functioni
Tyrosine-protein kinase implicated in the control of cell growth. Plays a role in the regulation of intracellular calcium levels (By similarity). Required in brain development and mature brain function with important roles in the regulation of axon growth, axon guidance, and neurite extension. Blocks axon outgrowth and attraction induced by ntn1 by phosphorylating its receptor ddc.By similarity1 Publication
Catalytic activityi
- EC:2.7.10.2PROSITE-ProRule annotation
Cofactori
Activity regulationi
Inhibited by phosphorylation of Tyr-531 by leukocyte common antigen and activated by dephosphorylation of this site.
