Product Overview
This rabbit polyclonal antibody targets megakaryocyte-associated tyrosine-protein kinase (gene MATK) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA.
MATK (also called CHK or CSK homologous kinase) is a non-receptor tyrosine kinase related to CSK. It phosphorylates the C-terminal inhibitory tyrosine of SRC-family kinases, keeping them in an inactive state. It is expressed in hematopoietic cells and brain and is studied as a negative regulator of SRC-family signaling in immune cells and neurons.
