  • 產(chǎn)品描述：

    This Mouse Mertk recombinant protein was produced in Mammalian cell, where the gene sequence encoding Mouse Mertk (19-497aa) was expressed with the C-terminal 10xHis tag. The purity of this Mertk protein was greater than 95% by SDS-PAGE. The activity has been validated.

    The mouse Mertk gene encodes a single-pass transmembrane protein with a relative molecular mass of about 110 KDa containing 994 amino acids. Mertk is a member of the receptor tyrosine kinase family, which is expressed in many tissues of the human body and participates in various physiological functions. Mertk is an important target in tumor therapy. Mertk reduces the phosphorylation levels of MAPK/ERK and PI3K/Akt, down-regulates the expression of BcH-2 protein, increases the cleavage of apoptosis-related protein caspase-3, and promotes cell apoptosis. The results of Twokoski et al. showed that Mertk could regulate the proliferation of melanoma cells by reducing the activation of Akt pathway and attenuating the activation of downstream signaling mammalian target of rapamycin and ribosomal protein S6 kinase, but had no significant effect on the activation of ERK pathway, suggesting that the effect of Mertk on melanoma proliferation is an Akt-dependent manner. Studies have shown that Mertk inhibitors can reduce glioblastoma cell adhesion, transform the cytoskeleton, and inhibit cell migration by up-regulating focal adhesion kinase phosphorylation and Ras homologous G protein activation.

靶點(diǎn)詳情

  • 功能：
    Receptor tyrosine kinase that transduces signals from the extracellular matrix into the cytoplasm by binding to several ligands including LGALS3, TUB, TULP1 or GAS6. Regulates many physiological processes including cell survival, migration, differentiation, and phagocytosis of apoptotic cells (efferocytosis). Ligand binding at the cell surface induces autophosphorylation of MERTK on its intracellular domain that provides docking sites for downstream signaling molecules. Following activation by ligand, interacts with GRB2 or PLCG2 and induces phosphorylation of MAPK1, MAPK2, FAK/PTK2 or RAC1. MERTK signaling plays a role in various processes such as macrophage clearance of apoptotic cells, platelet aggregation, cytoskeleton reorganization and engulfment. Functions in the retinal pigment epithelium (RPE) as a regulator of rod outer segments fragments phagocytosis. Plays also 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.
