Protein Structure

UniProt Annotation

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. {ECO:0000269PubMed:9171348}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:9171348}. Membrane {ECO:0000269PubMed:9171348}. Note=In platelets, 90% of MATK localizes to the membrane fraction, and translocates to the cytoskeleton upon thrombin stimulation.

Disease Associations

Tissue Specificity

Expressed in various myeloid cell lines, detected in brain and lung.
