Entrez Gene Summary for CTPS1 Gene

  • This gene encodes an enzyme responsible for the catalytic conversion of UTP (uridine triphosphate) to CTP (cytidine triphospate). This reaction is an important step in the biosynthesis of phospholipids and nucleic acids. Activity of this proten is important in the immune system, and loss of function of this gene has been associated with immunodeficiency. Alternative splicing results in multiple transcript variants.

GeneCards Summary for CTPS1 Gene

CTPS1 (CTP Synthase 1) is a Protein Coding gene. Diseases associated with CTPS1 include immunodeficiency 24. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include CTP synthase activity. An important paralog of this gene is CTPS2.

UniProtKB/Swiss-Prot for CTPS1 Gene

  • This enzyme is involved in the de novo synthesis of CTP, a precursor of DNA, RNA and phospholipids. Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as a source of nitrogen. This enzyme and its product, CTP, play a crucial role in the proliferation of activated lymphocytes and therefore in immunity.

Disorders for CTPS1 Gene

UniProtKB/Swiss-Prot

PYRG1_HUMAN
  • Immunodeficiency 24 (IMD24) [MIM:615897]: A life-threatening immunodeficiency, characterized by an impaired capacity of activated T and B cells to proliferate in response to antigen receptor-mediated activation. Patients have early onset of severe chronic viral infections, mostly caused by herpes viruses, including EBV and varicella zooster virus (VZV), and also suffer from recurrent encapsulated bacterial infections, a spectrum of infections typical of a combined deficiency of adaptive immunity. {ECO:0000269 PubMed:24870241}. Note=The disease is caused by mutations affecting the gene represented in this entry. A unique and recessive G to C mutation probably affecting a splice donor site at the junction of intron 17-18 and exon 18 has been identified in all patients. It results in expression of an abnormal transcript lacking exon 18 and a complete loss of the expression of the protein. {ECO:0000269 PubMed:24870241}.
