Predicted to enable carbohydrate kinase activity and phosphotransferase activity, alcohol group as acceptor. Predicted to be involved in carbohydrate phosphorylation and protein O-linked glycosylation. Predicted to act upstream of or within several processes, including learning or memory; nervous system development; and sensory perception of pain. Predicted to be integral component of membrane. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in congenital muscular dystrophy-dystroglycanopathy type A12 and limb-girdle muscular dystrophy. Orthologous to human POMK (protein O-mannose kinase). [provided by Alliance of Genome Resources, Apr 2022]
