Protein

Cytotoxic T-lymphocyte protein 4

Gene

CTLA4

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Inhibitory receptor acting as a major negative regulator of T-cell responses. The affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28.2 Publications

Involvement in diseasei

Systemic lupus erythematosus (SLE) [MIM:152700]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.2 Publications
Note: Disease susceptibility is associated with variations affecting the gene represented in this entry.
Genetic variations in CTLA4 may influence susceptibility to Graves disease, an autoimmune disorder associated with overactivity of the thyroid gland and hyperthyroidism.
Diabetes mellitus, insulin-dependent, 12 (IDDM12) [MIM:601388]: A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical features are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.1 Publication
Note: Disease susceptibility is associated with variations affecting the gene represented in this entry.
Celiac disease 3 (CELIAC3) [MIM:609755]: A multifactorial, chronic disorder of the small intestine caused by intolerance to gluten. It is characterized by immune-mediated enteropathy associated with failed intestinal absorption, and malnutrition. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes.2 Publications
Note: Disease susceptibility is associated with variations affecting the gene represented in this entry.

Pharmaceutical usei

Engineered fusion proteins consisting of the extracellular domain of CTLA4 and the IgG Fc region (Ctla4-Ig), inhibit T-cell-dependent antibody responses, and are used as immunosuppressive agents. They are soluble, have an enhanced affinity for B7 ligands and act as a competitive inhibitor of CD28.
