Function

Lecithin retinol acyltransferase is a microsomal enzyme that catalyzes the esterification of all-trans-retinol into all-trans-retinyl ester during phototransduction, an essential reaction for the retinoid cycle in visual system and vitamin A status in liver.

Clinical significance

Mutations in this gene have been associated with early-onset severe retinal dystrophy.[6]

LRAT was overexpressed in colorectal cancer cells compared to normal colonic epithelium. Strong LRAT expression was associated with a poor prognosis in patients with colorectal cancer.[7]
