MeSH note : phosphorylates C-terminal conserved Tyr of Src family members; from mouse brain; has
52% identity with mouse Csk; could play a significant role in the signal transduction
of hematopoietic cells; may regulate tyrosine kinase activity of SRC-family members
in brain by specifically phosphorylating their C-terminal regulatory tyrosine residue
which acts as a negative regulatory site; it may play an inhibitory role in the control
of T-cell proliferation; amino acid sequence given in first source; GenBank U05210;
RefSeq NM_010768;
