Transfers the acyl group from the sn-1 position of phosphatidylcholine to all-trans retinol, producing all-trans retinyl esters (PubMed:3410848).

Retinyl esters are storage forms of vitamin A (By similarity).

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 (By similarity).
