The protein encoded by this gene is a non-specific nucleoside triphosphatase that is slow-acting in vitro. This gene is overexpressed in many tumor tissues, and while it is not essential for the cell, overexpression is cytotoxic. However, the cytotoxicity is not related to its triphosphatase activity.NTPCR (Nucleoside-Triphosphatase, Cancer-Related) is a Protein Coding gene. Among its related pathways are Thiamine metabolism and superpathway of pyrimidine deoxyribonucleotides de novo biosynthesis. GO annotations related to this gene include poly(A) RNA binding and nucleoside-triphosphatase activity.
