MERTK Protein, Mouse (HEK293, His)

Mer Protein, a receptor tyrosine kinase, transduces signals by binding to ligands like LGALS3, TUB, TULP1, or GAS6. Crucial in processes such as cell survival, migration, differentiation, and apoptotic cell phagocytosis, Mer undergoes autophosphorylation upon ligand binding. This creates binding sites for downstream molecules, leading to interactions with GRB2 or PLCG2 and subsequent phosphorylation of MAPK1, MAPK2, FAK/PTK2, or RAC1. Mer signaling influences macrophage clearance, platelet aggregation, cytoskeleton reorganization, and engulfment. Notably, in the retinal pigment epithelium, Mer regulates phagocytosis of rod outer segment fragments. Additionally, Mer inhibits the innate immune response triggered by Toll-like receptors (TLRs) by activating STAT1, inducing the production of suppressors of cytokine signaling SOCS1 and SOCS3. MERTK Protein, Mouse (HEK293, His) is the recombinant mouse-derived MERTK protein, expressed by HEK293, with C-10*His labeled tag. The total length of MERTK Protein, Mouse (HEK293, His) is 479 a.a., with molecular weight of 55.0 kDa.

The Mer protein is a receptor tyrosine kinase that mediates cellular signaling from the extracellular matrix to the cytoplasm through binding to ligands such as LGALS3, TUB, TULP1, or GAS6. It plays a crucial role in various physiological processes, including cell survival, migration, differentiation, and the phagocytosis of apoptotic cells. Activation of Mer by ligand binding leads to autophosphorylation on its intracellular domain, creating binding sites for downstream signaling molecules. This, in turn, triggers interactions with GRB2 or PLCG2 and subsequent phosphorylation of MAPK1, MAPK2, FAK/PTK2, or RAC1. Mer signaling is involved in macrophage clearance of apoptotic cells, platelet aggregation, cytoskeleton reorganization, and engulfment. Notably, within the retinal pigment epithelium (RPE), Mer serves as a regulator of phagocytosis of rod outer segment fragments. Additionally, Mer plays a pivotal role in inhibiting the innate immune response triggered by Toll-like receptors (TLRs) by activating STAT1, which selectively induces the production of suppressors of cytokine signaling SOCS1 and SOCS3.
