GPAT3（glycerol-3-phosphate acyltransferase 3），癌症关联基因，基因ID：84803，该基因编码溶血磷脂酸酰基转移酶蛋白家族的一个成员。编码蛋白是一种在合成三酰甘油过程中催化甘油-3-磷酸转化为溶血磷脂酸的酶。已经鉴定出编码相同蛋白质的多个选择性剪接变体[由RefSeq提供，2012年1月]This gene encodes a member of the lysophosphatidic acid acyltransferase protein family. The encoded protein is an enzyme which catalyzes the conversion of glycerol-3-phosphate to lysophosphatidic acid in the synthesis of triacylglycerol. Multiple alternatively spliced variants， encoding the same protein， have been identified. [provided by RefSeq， Jan 2012]。
