Predicted to enable N-acylneuraminate cytidylyltransferase activity. Predicted to act upstream of or within CMP-N-acetylneuraminate biosynthetic process. Predicted to be located in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; liver; nervous system; and sensory organ. Used to study focal segmental glomerulosclerosis. Orthologous to human CMAS (cytidine monophosphate N-acetylneuraminic acid synthetase). [provided by Alliance of Genome Resources, Apr 2022]
