3.6.1.12 | generation of 3D models of DCTPP1 and its 5-methyl-dCTP-bound tetramer based on X-ray crystal structure of the tetrameric mouse dCTPase 1, PDB entry 2OIG. The cytosines of substrates 5-methyl-dCTP and dCTP bind deeply into the substrate pocket, which is composed of the residues from the dimer interface, including His38, Trp47, Glu63, Glu66, Trp73, Glu95, Asp98 and Tyr102 | Homo sapiens |

3.6.1.12 | physiological function | knockdown of DCTPP1 in breast cancer cell line MCF-7 cells remarkably retards proliferation and colony formation in vitro. The capacity of mammosphere formation of MCF-7 is suppressed with the silence of DCTPP1, consistent with the enhanced mammosphere-forming ability in DCTPP1-overexpressing MDA-MB-231 cells. The global methylation level is elevated in DCTPP1-knockdown MCF-7 cells or mammosphere-forming MCF-7 cells but decreased significantly in DCTPP1-overexpressing MDA-MB-231 cells and its mammosphere | Homo sapiens |
