Function

[DCTP1_MOUSE] Hydrolyzes deoxynucleoside triphosphates (dNTPs) to the corresponding nucleoside monophosphates. Has a strong preference for modified dCTP. Activity is highest with 5-iodo-dCTP, followed by 5-bromo-dCTP, unmodified dCTP, 5-methyl-dCTP and 5-chloro-dCTP. Hydrolyzes 2-chloro-dATP and 2-hydroxy-dATP with lower efficiency, and has even lower activity with unmodified dATP, dTTP and dUTP (in vitro). Does not hydrolyze ATP, UTP, ITP, GTP, dADP, dCDP or dGTP. May protect DNA or RNA against the incorporation of non-canonical nucleotide triphosphates. May protect cells against inappropriate methylation of CpG islands by DNA methyltransferases.^[1] ^[2]

Publication Abstract from PubMed

RS21-C6, which is highly expressed in all vertebrate genomes and green plants, is proposed to have nucleoside triphosphate pyrophosphohydrolase activity. Here, we report the crystal structures of the core fragment of RS21-C6, named RSCUT, and the complex with the substrate 5-methyl dCTP. The refined structure of RSCUT consists mainly of alpha-helices and shows formation of a tightly associated tetramer. On the basis of the structure of the RSCUT-m5dCTP complex and the results of pyrophosphatase activity assays, several key residues involved in the substrate binding of RS21-C6 have been identified. Tetramer formation is shown to be required for substrate binding.
