General description

The CTLA4 (cytotoxic T lymphocyte associated-4) gene is mapped to human chromosome 2q33. It is a glycoprotein found on T-cells and is homologous to CD28 (Cluster of Differentiation 28) at the juxtamembrane and cytoplasmic regions.

Immunogen

CTLA4 (NP_005205, 36 a.a. ~ 135 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

The CTLA4 (cytotoxic T lymphocyte associated-4) gene encodes a membrane receptor on cytotoxic T-cells that functions in T-cell apoptosis. It is a strong inhibitor of T-cell activation. It may be associated with type 1 diabetes. The gene has been identified as a susceptibility locus for Graves′ disease. It may be involved in the pathogenesis of autoimmune disorders.

Physical form

Solution in phosphate buffered saline, pH 7.4
