CTLA4 - cytotoxic T-lymphocyte associated protein 4 Gene
Also Known as CD; GSE; GRD4; ALPS5; CD152; CTLA-4; IDDM12; CELIAC3
Species: Homo sapiens
About CTLA4
This gene has 7 transcripts (splice variants), 157 orthologues, 1 paralogue and is associated with 11 phenotypes. Biased expression in lymph node (RPKM 10.3), appendix (RPKM 9.7) and 8 other tissues.
Summary
This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and Other autoimmune diseases.
