这个位点编码唾液酸转移酶编码的II型跨膜蛋白催化唾液酸从CMP转移到低聚糖底物该位点的多态性可能与精神分裂症患者利培酮反应的变化有关。另外，已经描述了剪接转录变体。[由RefSeq提供，2012年1月]
This locus encodes a sialyltransferase. The encoded type II transmembrane protein catalyzes the transfer of sialic acid from CMP to an oligosaccharide substrate. Polymorphisms at this locus may be associated with variations in risperidone response in schizophrenic patients. Alternatively spliced transcript variants have been described.
