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 Systemic Lupus Erythematosus and Rheumatoid Arthritis. Among its related pathways are CTLA4 Signaling and Th17 Differentiation Pathway. 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.

  • (Microbial infection) Acts as a receptor for adenovirus subgroup B.
