Bioinformation

Gene Symbol CD80
Gene Full Name CD80 molecule
Background 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]
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.

(Microbial infection) Acts as a receptor for adenovirus subgroup B. [UniProt]
Cellular Localization Membrane; Single-pass type I membrane protein. [UniProt]
Calculated MW 33 kDa
