Target
-
FunctionInvolved in the urea cycle of ureotelic animals where the enzyme plays an important role in removing excess ammonia from the cell.
-
Tissue specificityPrimarily in the liver and small intestine.
-
Involvement in diseaseDefects 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 similaritiesContains 2 ATP-grasp domains.
Contains 1 glutamine amidotransferase type-1 domain. -
DomainThe type-1 glutamine amidotransferase domain is defective.

Immunoprecipitation - Anti-CPS1 antibody (ab3682)CPS1 - Liver Mitochondrial Marker was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to CPS1 - Liver Mitochondrial Marker (ab3682) and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab3682.
Secondary: Antibody to Rabbit IgG light chain (HRP) (ab99697).
Band: 165kDa: CPS1. -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CPS1 antibody (ab3682)This image is a courtesy of Asha Sethab3682 staining CPS1 in mouse hepatic tissue section by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent paraformaldehyde fixation before heat mediated antigen retrieval in Citrate buffer and then blocked in maleate blocking solution for 30 minutes at 22°C. The primary antibody was diluted 1/500 and incubated with sample in maleate buffer blocking solution for 16 hours at 22°C. A Biotin conjugated donkey polyclonal to rabbit IgG was used at dilution at 1/250 as secondary antibody.

Immunohistochemistry (Frozen sections) - Anti-CPS1 antibody (ab3682)This image is a courtesy of Asha Sethab3682 staining CPS1 in mouse liver tissue section by Immunohistochemistry (Frozen sections). Tissue samples were fixed with paraformaldehyde and blocking with 100% maleate blocking solution at 220C for 30 minutes was performed. The sample was incubated with primary antibody (1/100) at 220C for 16 hours. An Alexa Fluor®488-conjugated donkey polyclonal to rabbit IgG was used undiluted as a secondary antibody. The image demonstrates CPS1 in green, nuclei stained blue with DAPI.
