MATK: Proteins and Enzymes

MATK, or Megakaryocyte-Associated Tyrosine-Protein Kinase, contains three isoforms that are 56 kDa, 57 kDa, and 52 kDa, and is involved in the regulation of tyrosine kinase and the inhibition of T-cell proliferation. MATK may play a role in signaling in certain types of breast cancer, and the protein is currently being used in research of a variety of diseases and disorders, including macular degeneration, endocarditis, neuroblastoma, colon cancer, ataxia, pharyngitis, pancreatitis, and pancreatic cancer. MATK is linked to the Kit Receptor signaling pathway, the IL-3 signaling pathway, the Neurotrophin signaling pathway, and ERBB2 signaling, through which it interacts with ERBB2, PTK2B, EWSR1, PXN, and SRC.
