Summary: Enables N-acylneuraminate cytidylyltransferase activity. Involved in CMP-N-acetylneuraminate biosynthetic process and N-acetylneuraminate metabolic process. Is active in nucleoplasm. 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, Dec 2024]

CRISPR/Cas9-mediated knock out of the CMAS gene, encoding a key enzyme in the sialylation pathway, in the mouse colorectal cancer MC38 cell line completely abrogated cell surface expression of sialic acids (MC38-Sia(null) ) and, unexpectedly, significantly increased in vivo tumor growth compared to the control MC38-MOCK cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
