Tyrosine-protein kinase Mer (MERTK) is a single-pass type I membrane protein which belongs to the MER/AXL/TYRO3 receptor kinase family. MERTK include two fibronectin type-III domains; two Ig-like C2-type domains; and one tyrosine kinase domain. It can’t be expressed in normal B- and T-lymphocytes; but it is usually expressed in numerous neoplastic B- and T-cell lines. MERTK could regulate many physiological processes; such as cell survival; migration; differentiation. It was demonstrated that the MERTK plays critical role in the engulfment and efficient clearance of apoptotic cells; platelet aggregation; and cytoskeleton reorganization. Not only these; it also plays an important role in inhibition of Toll-like receptors (TLRs)-mediated innate immune response by activating STAT1; which selectively induces production of suppressors of cytokine signaling SOCS1 and SOCS3. In addition; MERTK could regulate rod outer segments fragments phagocytosis in the retinal pigment epithelium (RPE); deficiency in MERTK are the cause of retinitis pigmentosa.
Recombinant Human MERTK is produced by our Mammalian expression system and the target gene encoding Met177-Ala499 is expressed with a 6His tag at the C-terminus.
