Non-receptor tyrosine-protein kinase which phosphorylates DOK1 on tyrosine residues . Also phosphorylates KHDRBS1/SAM68 and VIM on tyrosine residues . Phosphorylation of KHDRBS1 is EGF-dependent . Phosphorylates OTUB1, promoting deubiquitination of RPTOR .
Subcellular locations: Cytoplasm
Localizes to punctate cytoplasmic structures.
Highly expressed in most breast cancers (at protein level).
