CD80 which is a member of cell surface immunoglobulin superfamily takes part in the costimulatory signal essential for T-lymphocyte activation. CD80 binds to either human or mouse CD28 and CTLA-4 � binding to CD28 induces T-cell proliferation and cytokine production while binding to CTLA-4 inhibits T-cell activation. CD80 is expressed on activated B cells, activated T cells, and macrophages.

CD80 Human Recombinant produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 216 amino acids (35-242a.a.) and having a molecular mass of 24.9kDa (Molecular size on SDS-PAGE will appear at approximately 28-40kDa).CD80 is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

UniProt Protein Function:Involved in the costimulatory signal essential for T-lymphocyte activation. T-cell proliferation and cytokine production is induced by the binding of CD28, binding to CTLA-4 has opposite effects and inhibits T-cell activation.
NCBI Summary:The protein encoded by this gene is a membrane receptor that is activated by the binding of CD28 or CTLA-4. The activated protein induces T-cell proliferation and cytokine production. This protein can act as a receptor for adenovirus subgroup B and may play a role in lupus neuropathy. [provided by RefSeq, Aug 2011]
