An oncogene related to src and thought to be important in brain development (fyn mutation inhibits positive turning responses to netrin) and function (fyn mutants seem to have defects in long-term potentiation). Also has a role in T-cell signalling in association with lck. It encodes a nonreceptor tyrosine kinase. See rak (fyn-related kinase).
