CTPS2 Products

The protein encoded by the CTPS2 gene catalyzes the formation of CTP from UTP with the concomitant deamination of glutamineto glutamate. This protein is the rate-limiting enzyme in the synthesis of cytosine nucleotides, which play animportant role in various metabolic processes and provide the precursors necessary for the synthesis of RNA and DNA.Cancer cells that exhibit increased cell proliferation also exhibit an increased activity of this encoded protein.Thus, this protein is an attractive target for selective chemotherapy. Three alternatively spliced transcript variantsencoding the same protein have been described for this gene. (provided by RefSeq)
