Description
Product Characteristics:
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.
Subcellular location: Cell membrane
Synonyms: B7, BB1, B7-1, B7.1, LAB7, CD28LG, CD28LG1, T-lymphocyte activation antigen CD80, Activation B7-1 antigen, CTLA-4 counter-receptor B7.1, CD80
Target Information: 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.
