Kinase: CTK megakaryocyte-associated tyrosine kinase

Group: TK      Family: Csk      

Description: megakaryocyte-associated tyrosine kinase

Gene Symbol: MATK

Synonyms: CHK, CTK, DKFZp434N1212, HHYLTK, HYL, HYLTK, Lsk, MGC1708, MGC2101

UniprotKB/SwissProt: MATK_HUMAN (P42679)

Function: 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.

Subcellular Localization: Cytoplasm.
