NCBI Protein Information
membrane bound O-acyl transferase (MBOAT) family protein
NCBI Summary
Encodes Acyl-CoA:diacylglycerol acyltransferase (DGAT) catalyzes the final step of the triacylglycerol synthesis pathway. An insertion mutation in the TAG1 gene results in altered lipid phenotype. Role in senescence and seed development. Its preferred substrate is linolenoyl-CoA (C18:3-CoA).

UniProt Comments
Major contributor to triacylglycerol (TAG) synthesis and oil accumulation in seeds. Catalyzes the acylation of the sn-3 hydroxy group of sn-1,2-diacylglycerol using acyl-CoA (PubMed:10571850, PubMed:10580283, PubMed:10601854, PubMed:11402213, PubMed:12114588, PubMed:20040537, PubMed:20101470). Can use palmitoyl-CoA and oleoyl-CoA as substrates (PubMed:20101470). Can use oleoyl-CoA and linoleoyl-CoA as substrates. Has substrate preference for oleoyl-CoA compared to linoleoyl-CoA (PubMed:23770095). Has complementary functions with PDAT1 that are essential for triacylglycerol synthesis and normal development of both seeds and pollen (PubMed:20040537).
