MERTK (cMER) [A708S] Recombinant Human Protein

MERTK (c-MER) is a member of the TYRO3/AXL/MER (TAM) receptor kinase family which encodes a transmembrane protein with two fibronectin type-III domains, two Ig-like C2-type (immunoglobulin-like) domains, and one tyrosine kinase domain. Cytokine-dependent activation of TAM signaling diverts a proinflammatory pathway to provide an intrinsic feedback inhibitor of both TLR- and cytokine-driven immune responses. MERTK is essential regulators of mammalian spermatogenesis. Mutations in MERTK gene have been associated with disruption of the retinal pigment epithelium (RPE) phagocytosis pathway and onset of autosomal recessive retinitis pigmentosa (RP). Recombinant human MERTK A708S (578-872) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.

ALK Recombinant Human Protein

Anaplastic Lymphoma Receptor Tyrosine Kinase (ALK) belongs to the insulin receptor superfamily. It is vital for brain development. Mutations, rearrangements, and amplifications in the ALK gene have been found in tumors, including anaplastic large cell lymphoma, neurblastoma, and non-small cell lung cancer. Chromosomal rearrangement is the most common genetic alteration.

MET (cMET) Y1235D Recombinant Human Protein (Invitrogen™)

This MET (cMET) Y1235D recombinant human protein (956–end) was expressed in insect cells. MET receptor tyrosine kinase is a proto-oncogene that encodes a transmembrane growth factor receptor which is a heterodimer of two disulphide linked chains of 50 kDa (alpha) and 145 kDa (beta). MET is widely expressed in the kidney, brain, lung, skin, and embryonic tissue. Hepatocyte growth factor (HGF) binds to MET and activates its tyrosine kinase activity. MET is overexpressed and activated in a variety of human cancers including pancreatic, colon, gastric, cervical and ovarian cancers and has been shown to be involved in tumor cell migration and invasion. MET (Y1235D) is one of the native mutant forms of MET. MET (cMET) Y1235D recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service.

RET A883F Recombinant Human Protein (Invitrogen™)

This RET A883F recombinant human protein (658–end) was expressed in insect cells. RET receptor tyrosine kinase or ret proto-oncogene is a member of the cadherin superfamily which are cell-surface receptors that transduce signals for cell growth and differentiation. RET can undergo oncogenic activation in vivo and in vitro by cytogenetic rearrangement. Mutations in the RET gene are associated with the disorders multiple endocrine neoplasia, type IIA, multiple endocrine neoplasia, type IIB, Hirschsprung disease, and medullary thyroid carcinoma. RET signaling pathway, by regulating the development of both the nervous and lymphoid system in the gut, plays a key role in the molecular mechanisms that orchestrate intestine organogenesis. RET A883F recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service.

EGFR (ErbB1) G719C Recombinant Human Protein (Invitrogen™)

This EGFR (ErbB1) G719C recombinant human protein (672–end) was expressed in insect cells. EGFR receptor tyrosine kinase is a transmembrane glycoprotein. Binding of epidermal growth factor to EGFR induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation, differentiation, motility, and cell survival. Activation of EGFR triggers mitogenic signaling in gastrointestinal mucosa, and its expression is upregulated in colon cancers and most neoplasms. Activation of EGFR triggers activation of the ERK-signaling pathway in normal gastric epithelial and colon cancer cell lines. Inactivation of EGFR with selective inhibitors significantly reduces ERK2 activation, c-fos mRNA expression and cell proliferation. EGFR (ErbB1) G719C recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service.
