Summaries for CD80 Gene

Entrez Gene Summary for CD80 Gene

  • 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]

GeneCards Summary for CD80 Gene

CD80 (CD80 Molecule) is a Protein Coding gene. Diseases associated with CD80 include sialadenitis and lymphocytic choriomeningitis. Among its related pathways are PI-3K cascade and PI-3K cascade. GO annotations related to this gene include coreceptor activity. An important paralog of this gene is CD86.

UniProtKB/Swiss-Prot for CD80 Gene

  • 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.
