Specificity / Sensitivity
CMTM4 Antibody recognizes endogenous levels of total CMTM4 protein. This antibody does not cross-react with CMTM6 protein.
Species Reactivity:
Human, Mouse
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Hamster, Bovine
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu202 of human CMTM4 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
CKLF-like MARVEL transmembrane domain-containing protein 4 (CMTM4) is a member of the chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing family (1). CMTM4 acts as a tumor suppressor in various malignancies, and regulates cell growth and transition through the cell cycle in HeLa cells (1-4). CMTM4 plays an important role in angiogenesis, enabling internalization of membrane-bound vascular endothelial cadherin at adherens junctions, mediating endothelial barrier function, and controlling vascular sprouting (5). In the immune system, CMTM4 acts as a backup for CMTM6 to regulate plasma membrane expression of PD-L1, an immune inhibitory ligand critical for immune tolerance to self and anti-tumor immunity (6-8). CMTM4 may also protect PD-L1 from being polyubiquitinated and targeted for degradation (8). Due to the roles of CMTM4 in the immune system and as a tumor suppressor, it is being investigated as a therapeutic target for the treatment of cancer.
