Predicted to enable adenylate kinase activity; cytidylate kinase activity; and nucleoside diphosphate kinase activity. Predicted to be involved in nucleoside diphosphate phosphorylation and nucleoside triphosphate biosynthetic process. Predicted to act upstream of or within several processes, including axoneme assembly; epithelial cilium movement involved in extracellular fluid movement; and inflammatory response to antigenic stimulus. Predicted to be located in extracellular region. Human ortholog(s) of this gene implicated in spermatogenic failure 27. Orthologous to human AK7 (adenylate kinase 7).
