CPS1 - carbamoyl-phosphate synthase 1 Gene
Also Known as PHN; GATD6; CPSASE1
Species: Homo sapiens
About CPS1
This gene has 15 transcripts (splice variants), 196 orthologues, 2 paralogues and is associated with 4 phenotypes. Biased expression in liver (RPKM 281.3), duodenum (RPKM 102.6) and 1 other tissue.
Summary
The mitochondrial enzyme encoded by this gene catalyzes synthesis of carbamoyl phosphate from ammonia and bicarbonate. This reaction is the first committed step of the urea cycle, which is important in the removal of excess urea from cells. The encoded protein may also represent a core mitochondrial nucleoid protein. Three transcript variants encoding different isoforms have been found for this gene. The shortest isoform may not be localized to the mitochondrion. Mutations in this gene have been associated with carbamoyl phosphate synthetase deficiency, susceptibility to persistent pulmonary hypertension, and susceptibility to venoocclusive disease after bone marrow transplantation.[provided by RefSeq, May 2010]
