A family of protein tyrosine kinases involved in cellular control, src having been the first one described (see src gene). All cells have one at least of these kinases which have characteristic domains (see SH domains). Phosphorylation of a src tyrosine residue by csk allows the SH2 domain to bind and block activity. Members of the family include blk, chk, fgr, fyn, hck, lyn, p57lck, and yes.
