CTK 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. Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily. Expressed in various myeloid cell lines, detected in brain and lung. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
