CAD Polyclonal Antibody

The de novo synthesis of pyrimidine nucleotides is required for mammalian cells to proliferate. CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase) encodes a trifunctional protein which is associated with the enzymatic activities of the first 3 enzymes in the 6-step pathway of pyrimidine biosynthesis: carbamoylphosphate synthetase (CPS II), aspartate transcarbamoylase, and dihydroorotase. This protein is regulated by the mitogen-activated protein kinase (MAPK) cascade, which indicates a direct link between activation of the MAPK cascade and de novo biosynthesis of pyrimidine nucleotides. Alternative splicing results in multiple transcript variants encoding different isoforms.
