Predicted to enable D-ribitol-5-phosphate cytidylyltransferase activity and protein homodimerization activity. Predicted to be involved in protein O-linked mannosylation. Predicted to act upstream of or within axon guidance and protein glycosylation. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in autosomal recessive limb-girdle muscular dystrophy type 2U and congenital muscular dystrophy-dystroglycanopathy A7. Orthologous to human CRPPA (CDP-L-ribitol pyrophosphorylase A). [provided by Alliance of Genome Resources, Apr 2022]
