| Tissue Specificity | Highest expression in adipose tissue. Also detected in heart, skeletal muscle, and portions of the gastrointestinal tract. Detected in normal retina and retinoblastoma cells. Detected in retinal pigment epithelium and, at lower intensity, in the inner segments of photoreceptors and in the ganglion cell layer of the neural retina (at protein level). |
| Post Translational Modifications | Phosphorylation at Ser-404 by PKA is increased during fasting and moderate intensity exercise, and moderately increases lipolytic activity. Phosphorylation at Ser-404 is increased upon beta-adrenergic stimulation. Ubiquitinated by PEX2 in response to reactive oxygen species (ROS), leading to its degradation. Ubiquitination is stimulated by LDAH. |
| Function | Catalyzes the initial step in triglyceride hydrolysis in adipocyte and non-adipocyte lipid droplets. Exhibits a strong preference for the hydrolysis of long-chain fatty acid esters at the sn-2 position of the glycerol backbone and acts coordinately with LIPE/HLS and DGAT2 within the lipolytic cascade. Also possesses acylglycerol transacylase and phospholipase A2 activities. Transfers fatty acid from triglyceride to retinol, hydrolyzes retinylesters, and generates 1,3-diacylglycerol from triglycerides. Regulates adiposome size and may be involved in the degradation of adiposomes. Catalyzes the formation of an ester bond between hydroxy fatty acids and fatty acids derived from triglycerides or diglycerides to generate fatty acid esters of hydroxy fatty acids (FAHFAs) in adipocytes. Acts antagonistically with LDAH in regulation of cellular lipid stores. Inhibits LDAH-stimulated lipid droplet fusion. May play an important role in energy homeostasis. May play a role in the response of the organism to starvation, enhancing hydrolysis of triglycerides and providing free fatty acids to other tissues to be oxidized in situations of energy depletion. |
