Western blot analysis of DCTD over-expressed 293 cell line, cotransfected with DCTD Validated Chimera RNAi ( Cat # H00001635-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with DCTD monoclonal antibody (M01), clone 4B9 (Cat # H00001635-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene catalyzes the deamination of dCMP to dUMP, the nucleotide substrate for thymidylate synthase. The encoded protein is allosterically activated by dCTP and inhibited by dTTP, and is found as a homohexamer. This protein uses zinc as a cofactor for its activity. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq
