NUDT18（nudix hydrolase 18），癌症关联基因，基因ID：79873，这个基因编码的蛋白质是Nudix水解酶家族的一员Nudix水解酶消除了来自细胞的潜在毒性核苷酸代谢物，并调节了许多不同核苷酸底物、辅因子和信号分子的浓度和可用性。该蛋白质含有Nudix水解酶结构域，并水解氧化形式的鸟苷和脱氧鸟苷二磷酸盐。[由RefSeq提供，2012年9月]The protein encoded by this gene is a member of the Nudix hydrolase family. Nudix hydrolases eliminate potentially toxic nucleotide metabolites from the cell and regulate the concentrations and availability of many different nucleotide substrates， cofactors， and signaling molecules. This protein contains a Nudix hydrolase domain and hydrolyzes oxidized forms of guanosine and deoxyguanosine diphosphates. [provided by RefSeq， Sep 2012]。
