  • Target

    • Function

      Involved in the urea cycle of ureotelic animals where the enzyme plays an important role in removing excess ammonia from the cell.
    • Tissue specificity

      Primarily in the liver and small intestine.
    • Involvement in disease

      Defects in CPS1 are the cause of carbamoyl phosphate synthetase 1 deficiency (CPS1D) [MIM:237300]. CPS1D is an autosomal recessive disorder of the urea cycle causing hyperammonemia. Clinical features include protein intolerance, intermittent ataxia, seizures, lethargy, developmental delay and mental retardation.
      Note=Genetic variations in CPS1 influence the availability of precursors for nitric oxide (NO) synthesis and play a role in clinical situations where endogenous NO production is critically important, such as neonatal pulmonary hypertension, increased pulmonary artery pressure following surgical repair of congenital heart defects or hepatovenocclusive disease following bone marrow transplantation. Infants with neonatal pulmonary hypertension homozygous for Thr-1406 have lower L-arginine concentrations than neonates homozygous for Asn-1406.
    • Sequence similarities

      Contains 2 ATP-grasp domains.
      Contains 1 glutamine amidotransferase type-1 domain.
    • Domain

      The type-1 glutamine amidotransferase domain is defective.
