Entrez Gene Summary for TCIRG1 Gene

  • Through alternate splicing, this gene encodes two proteins with similarity to subunits of the vacuolar ATPase (V-ATPase) but the encoded proteins seem to have different functions. V-ATPase is a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, and receptor-mediated endocytosis. V-ATPase is comprised of a cytosolic V1 domain and a transmembrane V0 domain. Mutations in this gene are associated with infantile malignant osteopetrosis. [provided by RefSeq, Jul 2008]

GeneCards Summary for TCIRG1 Gene

TCIRG1 (T-Cell, Immune Regulator 1, ATPase, H+ Transporting, Lysosomal V0 Subunit A3) is a Protein Coding gene. Diseases associated with TCIRG1 include osteopetrosis, autosomal recessive 1 and tcirg1-related autosomal recessive osteopetrosis. Among its related pathways are Signaling by GPCR and Insulin receptor signalling cascade. GO annotations related to this gene include transporter activity and hydrogen ion transmembrane transporter activity. An important paralog of this gene is ATP6V0A1.

Disorders for TCIRG1 Gene

  • Osteopetrosis, autosomal recessive 1 (OPTB1) [MIM:259700]: A rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. Osteopetrosis occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Recessive osteopetrosis commonly manifests in early infancy with macrocephaly, feeding difficulties, evolving blindness and deafness, bone marrow failure, severe anemia, and hepatosplenomegaly. Deafness and blindness are generally thought to represent effects of pressure on nerves. {ECO:0000269 PubMed:11532986, ECO:0000269 PubMed:12552563, ECO:0000269 PubMed:15300850}. Note=The disease is caused by mutations affecting the gene represented in this entry.
