The function of SRMS (src-related kinase lacking C-terminal regulatory tyrosine and N-terminal myristylation sites, Ensembl gene identifier ENSG00000125508) is as follows. Non-receptor tyrosine-protein kinase which phosphorylates DOK1 on tyrosine residues (PubMed:23822091). Also phosphorylates KHDRBS1/SAM68 and VIM on tyrosine residues (PubMed:29496907). Phosphorylation of KHDRBS1 is EGF-dependent (PubMed:29496907). Phosphorylates OTUB1, promoting deubiquitination of RPTOR (PubMed:35927303). {ECO:0000269|PubMed:23822091, ECO:0000269|PubMed:29496907, ECO:0000269|PubMed:35927303}.
