Rabbit anti-Human CMTM6 Monoclonal Antibody

Uniprot Id

Q9NX76

Target Species

Human

Target Name

CMTM6

Target Full Name

CKLF-like MARVEL transmembrane domain-containing protein 6

Target Function

Master regulator of recycling and plasma membrane expression of PD-L1/CD274, an immune inhibitory ligand critical for immune tolerance to self and antitumor immunity. Associates with both constitutive and IFNG-induced PD-L1/CD274 at recycling endosomes, where it protects PD-L1/CD274 from being targeted for lysosomal degradation, likely by preventing its STUB1-mediated ubiquitination. May stabilize PD-L1/CD274 expression on antigen presenting cells and potentiates inhibitory signaling by PDCD1/CD279, its receptor on T-cells, ultimately triggering T-cell anergy.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein. Early endosome membrane; Multi-pass membrane protein. Recycling endosome membrane; Multi-pass membrane protein.

Target Protein Families

Chemokine-like factor family

Target Tissue Specificity

Expressed in the leukocytes, placenta and testis.

Target Synonyms

CMTM6; CKLFSF6; CKLF-like MARVEL transmembrane domain-containing protein 6; Chemokine-like factor superfamily member 6

Target Background

This gene belongs to the chemokine-like factor gene superfamily, a novel family that is similar to the chemokine and transmembrane 4 superfamilies. This gene is one of several chemokine-like factor genes located in a cluster on chromosome 3. This gene is widely expressed in many tissues, but the exact function of the encoded protein is unknown.
