Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

In adipose tissue and heart, it primarily hydrolyzes stored triglycerides to free fatty acids, while in steroidogenic tissues, it principally converts cholesteryl esters to free cholesterol for steroid hormone production.

Catalytic activityi

Diacylglycerol + H2O = monoacylglycerol + a carboxylate.
Triacylglycerol + H2O = diacylglycerol + a carboxylate.
Monoacylglycerol + H2O = glycerol + a carboxylate.

Enzyme regulationi

Rapidly activated by cAMP-dependent phosphorylation under the influence of catecholamines. Dephosphorylation and inactivation are controlled by insulin.

Pathwayi: triacylglycerol degradation

This protein is involved in the pathway triacylglycerol degradation, which is part of Glycerolipid metabolism.
View all proteins of this organism that are known to be involved in the pathway triacylglycerol degradation and in Glycerolipid metabolism.
