Transfers the acyl group from the sn-1 position of phosphatidylcholine to all-trans retinol, producing all-trans retinyl esters. Retinyl esters are storage forms of vitamin A (PubMed:28758396). LRAT plays a critical role in vision (By similarity). It provides the all-trans retinyl ester substrates for the isomerohydrolase which processes the esters into 11-cis-retinol in the retinal pigment epithelium; due to a membrane-associated alcohol dehydrogenase, 11 cis-retinol is oxidized and converted into 11-cis-retinaldehyde which is the chromophore for rhodopsin and the cone photopigments (By similarity). Required for the survival of cone photoreceptors and correct rod photoreceptor cell morphology (PubMed:25416279). a 1,2-diacyl-sn-glycero-3-phosphocholine + all-trans-retinol--[retinol-binding protein] = a 2-acyl-sn-glycero-3-phosphocholine + an all-trans-retinyl ester + apo--[retinol-binding protein] 1,2-diheptanoyl-sn-glycero-3-phosphocholine + all-trans-retinol--[retinol-binding protein] = 2-heptanoyl-sn-glycero-3-phosphocholine + all-trans-retinyl heptanoate + apo--[retinol-binding protein] 1,2-dioctanoyl-sn-glycero-3-phosphocholine + all-trans-retinol--[retinol-binding protein] = 2-octanoyl-sn-glycero-3-phosphocholine + all-trans-retinyl octanoate + apo--[retinol-binding protein] 1,2-dihexadecanoyl-sn-glycero-3-phosphocholine + all-trans-retinol--[retinol-binding protein] = 2-hexadecanoyl-sn-glycero-3-phosphocholine + all-trans-retinyl hexadecanoate + apo--[retinol-binding protein] 1,2-didodecanoyl-sn-glycero-3-phosphocholine + all-trans-retinol--[retinol-binding protein] = 2-dodecanoyl-sn-glycero-3-phosphocholine + all-trans-retinyl dodecanoate + apo--[retinol-binding protein] 1,2-dihexadecanoyl-sn-glycero-3-phosphocholine + all-trans-retinol = all-trans-retinyl hexadecanoate + hexadecanoyl-sn-glycero-3-phosphocholine Inhibited by all-trans-retinyl alpha-bromoacetate and N-boc-L-biocytinyl-11-aminoundecane chloro-methyl ketone (BACMK). Cofactor metabolism; retinol metabolism. Present in the rough endoplasmic reticulum and multivesicular body in hepatic stellate cells. Present in the rough endoplasmic reticulum and perinuclear region in endothelial cells (By similarity). Hepatic stellate cells and endothelial cells (at protein level). LRAT activity is up-regulated by dietary vitamin A (By similarity). Under conditions of vitamin A depletion, LRAT expression in the liver is induced by retinoic acid. Knockout mice are viable (PubMed:25416279). Knockout mice at one month of age show loss of nearly all cone photoreceptors in the central and ventral retina (PubMed:25416279). Surviving cone cells show severe degeneration, the dorsal retinal also exhibits a significant reduction in cone photoreceptors (PubMed:25416279). At one month of age rod photoreceptors show shorter outer segments (PubMed:25416279). Nearly all cone photoreceptors are lost by six months of age (PubMed:25416279). Remaining cone cells show disrupted structures with the majority showing abnormal cell bodies or lack of an outer segment (PubMed:25416279). Belongs to the H-rev107 family.
