这个基因编码的线粒体酶催化氨和碳酸氢盐合成氨甲酰磷酸酯。该反应是尿素循环的第一步，对去除细胞中多余的尿素非常重要。编码的蛋白质也可能代表核心线粒体类核蛋白。已经发现了三个编码不同亚型的转录变体最短的亚型可能不局限于线粒体。该基因突变与氨甲酰磷酸酯合成酶缺乏、对持续性肺动脉高压的易感性以及骨髓移植后对静脉阻塞性疾病的易感性有关。
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]
