anti-CD152 / CTLA4 antibody [WKH203]

anti-CD152 / CTLA4 antibody [WKH203] for ELISA,Flow cytometry,Western blot and Rat

Overview

Product Description Mouse Monoclonal antibody [WKH203] recognizes CD152 / CTLA4
Mouse anti Rat CD152 antibody, clone WKH203 recognizes rat CD152, also known as cytoxic-T-lymphocyte antigen-4 (CTLA-4), which is similar in structure to CD28 and also binds ligands CD80 and CD86. CD152 is expressed by activated T-lymphocytes and studies also suggest expression by regulatory T-lymphocytes (Lin and Hunig 2003).

Bioinformation

Gene Symbol Ctla4
Gene Full Name cytotoxic T-lymphocyte-associated protein 4
Background This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

Function Inhibitory receptor acting as a major negative regulator of T-cell responses. The affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28. [UniProt]
Calculated MW 25 kDa
PTM N-glycosylation is important for dimerization.

Phosphorylation at Tyr-201 prevents binding to the AP-2 adapter complex, blocks endocytosis, and leads to retention of CTLA4 on the cell surface. [UniProt]
