Type: | Family | Name: | Uridine-cytidine kinase 1 |
Description: | Uridine-cytidine kinase (UCK), also known as uridine kinase, phosphorylates uridine and cytidine to uridine monophosphate (UMP) and cytidine monophosphate (CMP) []. UCK is the rate-limiting enzyme in the pyrimidine-nucleotide salvage pathway. It also catalyses the phosphorylation of several cytotoxic ribonucleoside analogs that have been investigated for possible use as chemotherapeutic agents for treatment of cancer [, , ].Two UCKs with 70% sequence identity have been reported in human: UCK1 and UCK2. This entry represents UCK1. The biological role of UCK1 remains unknown, as UCK2 is responsible for the majority or uridine and cytidine phosphorylation in cells [, ]. | Short Name: | UCK-1 |
