Function

GPAT4 is involved in the biosynthesis of triglycerides.^[6] The majority of triglycerides are synthesised from glycerol 3-phosphate (G3P) via the addition of three fatty acyl-CoA substrates, which are made from fatty acids. The first of these additions is catalysed by glycerol-3-phosphate acyltransferases (GPATs: EC 2.3.1.15), including GPAT4, yielding lysophosphatidic acid.^[7] GPAT4 has been shown to be important for lactation, with quantitative trait locus (QTL) for several milk production and composition traits observed at this locus in cattle.^[8]
