Protein function (UniProt)

CMP-sialic acid transporter

Transports CMP-sialic acid from the cytosol into the Golgi apparatus, functioning as an antiporter that exchanges CMP-sialic acid for CMP (PubMed:12682060, PubMed:15576474, PubMed:23873973). Binds both CMP-sialic acid and free CMP, but has higher affinity for free CMP (By similarity). Also able to exchange CMP-sialic acid for AMP and UMP (PubMed:12682060). Also mediates the transport of CDP-ribitol (By similarity)
