GeneCards Summary for AK8 Gene

AK8 (Adenylate Kinase 8) is a Protein Coding gene. Among its related pathways are Pyrimidine metabolism (KEGG) and Metabolism. Gene Ontology (GO) annotations related to this gene include nucleoside diphosphate kinase activity and cytidylate kinase activity. An important paralog of this gene is AK2.

UniProtKB/Swiss-Prot for AK8 Gene

  • Nucleoside monophosphate (NMP) kinase that catalyzes the reversible transfer of the terminal phosphate group between nucleoside triphosphates and monophosphates. Has highest activity toward AMP, and weaker activity toward dAMP, CMP and dCMP. Also displays broad nucleoside diphosphate kinase activity.
