2.3.1.135	physiological function	downregulation of LRAT expression in rat hepatic stellate cells is required for mobilization of retinyl ester in liver injury for tissue repair and wound healing, interleukin-1 is a potent suppressor of LRAT with a hierarchy role in the transcriptional regulation, interleukin-1 does not regulate the stability of LRAT protein. Interleukin-1 is a key mediator to down-regulate LRAT in liver injury	720839	
2.3.1.135	physiological function	function of LRAT is to catalyze a trans-esterification reaction that occurs between the sn-1 position of lecithin molecules in the lipid bilayer of the smooth endoplasmic reticulum and all-trans-retinol in the formation of all-trans-retinyl esters. Functional role of LRAT in the visual cycle	719417	
2.3.1.135	physiological function	lecithin:retinol acyltransferase is critical for cellular uptake of vitamin A from serum retinol-binding protein, which depends on functional coupling of STRA6 with intracellular lecithin:retinol acyltransferase. Vitamin A uptake is regulated by all-trans-retinoic acid in nonocular tissues of mice. When in excess, vitamin A is rapidly taken up and converted to its inert ester form in peripheral tissues, such as lung, whereas in vitamin A deficiency, ocular retinoid uptake is favored	-, 720030	
2.3.1.135	physiological function	lecithin:retinol acyltransferase, LRAT, is a membrane-bound protein that plays an essential function in the visual cycle. It catalyzes the esterification of retinol into retinyl esters in the retinal pigment epithelium as well as in other tissues including testis, liver, and intestine	720353	
2.3.1.135	physiological function	quiescent LRAT knockout hepatic stellate cells retain the capacity to synthesize retinyl esters and to store neutral lipids in lipid droplets ex vivo. The median lipid droplet size in LRAT knockout hepatic stellate cells (1080 nm) is significantly smaller than in wild-type stellate cells (1618 nm). Upon prolonged (24h) incubation, the amounts of small (less than 700 nm) lipid droplets strongly increases both in wild type and in LRAT knockout hepatic stellate cells	756085	
2.3.1.135	physiological function	relationship between LRAT and Crbp1 during retinyl ester biosynthesis in which mitochondria associated membranes-associated Crpb1 and LRAT colocalize, and both surround the growing retinyl ester-containing lipid droplet. The N-terminus of LRAT, especially K36 and R38, is essential to colocalization with the lipid droplet	718992	
2.3.1.135	physiological function	retinoid isomerohydrolase RPE65 palmitoylation level is highly regulated by lecithin:retinol acyltransferase (LRAT) enzyme. In the presence of LRAT substrate all-trans retinol, there is a significant decrease in the level of palmitoylation of RPE65	758452
