Previous GeneCards Identifiers for ICOS Gene
The protein encoded by this gene belongs to the CD28 and CTLA-4 cell-surface receptor family. It forms homodimers and plays an important role in cell-cell signaling, immune responses, and regulation of cell proliferation. [provided by RefSeq, Jul 2008]
GeneCards Summary for ICOS Gene
ICOS (Inducible T-Cell Co-Stimulator) is a Protein Coding gene. Diseases associated with ICOS include immunodeficiency, common variable, 1 and common variable immunodeficiency. Among its related pathways are Cell adhesion molecules (CAMs) and Allograft rejection.
UniProtKB/Swiss-Prot for ICOS Gene
Enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells. Essential both for efficient interaction between T and B-cells and for normal antibody responses to T-cell dependent antigens. Does not up-regulate the production of interleukin-2, but superinduces the synthesis of interleukin-10. Prevents the apoptosis of pre-activated T-cells. Plays a critical role in CD40-mediated class switching of immunoglobin isotypes (By similarity).
