Predicted to enable D-ribitol-5-phosphate cytidylyltransferase activity and protein homodimerization activity. Acts upstream of or within axon guidance and protein glycosylation. Predicted to be located in cytoplasm. Predicted to be active in cytosol. Is expressed in brain. 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]
