<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Specifically catalyzes coenzyme A (CoA)-dependent acylation of 1-acyl-sn-glycerol 3-phosphate (2-lysophosphatidic acid/LPA) to generate phosphatidic acid (PA), an important metabolic intermediate and precursor for both triglycerides and glycerophospholipids. Does not esterify other lysophospholipids. Acyl donors are long chain (at least C16) fatty acyl-CoAs: arachidonoyl-CoA, linoleoyl-CoA, oleoyl-CoA and at a lesser extent palmitoyl-CoA (PubMed:22560221).

Additionally possesses low triacylglycerol lipase and CoA-independent acylglycerol transacylase activities and thus may play a role in acyl-chain remodeling of triglycerides (PubMed:15364929, PubMed:20034933, PubMed:22560221).

Has hydrolytic activity against glycerolipids triacylglycerol, diacylglycerol and monoacylglycerol, with a strong preference for oleic acid as the acyl moiety (PubMed:21878620).

Caution

Variant Met-148 was initially reported to reduce triglyceride hydrolysis activity in vitro (PubMed:20034933, PubMed:21878620). However further in vitro and in vivo data demonstrated that it actually does not affect triglyceride hydrolysis activity, but rather increases 1-acylglycerol-3-phosphate O-acyltransferase activity (PubMed:22560221).3 Publications

Disease susceptibility is associated with variants affecting the gene represented in this entry.
Disease descriptionA condition characterized by accumulation of triglycerides in the liver. It is associated with adverse metabolic consequences, including insulin resistance and dyslipidemia. In a subset of individuals, hepatic steatosis promotes an inflammatory response in the liver, referred to as steatohepatitis, which can progress to cirrhosis and liver cancer. NAFLD is the most common form of liver disease in Western countries.

Polymorphic variation at position 148 influences insulin secretion levels and obesity. In obese subjects the body mass index and waist are higher in carriers of the Ile-148 allele. The Ile-148 carriers also display decreased insulin secretion in response to oral glucose tolerance test. Met-148 allele carriers are seemingly more insulin resistant at a lower body mass index.1 Publication
