Sks lrat. O'Byrne et al. show that the livers of LRAT-deficient mice have undetectable levels of retinyl ester and are completely void of lipid droplets . These studies not only proved that LRAT is the only retinol esterifying enzyme present in the liver, but also that LRAT and/or its product retinyl ester is necessary for HSC lipid droplet formation.

Leber congenital amaurosis (LCA) is the second most common group of inherited retinal dystrophies after retinitis pigmentosa, accounting for about 5% of all retinal dystrophies. With an estimated prevalence ranging from 1 per 33,000 2 to 1 per 81,000, 3 LCA accounts for about 20% of legal blindness in children. 4.

However, in tissues where LRAT is not active (such as mammary gland), and in those where the low V max of LRAT can be limiting under a high retinol status (such as HSC), ARAT activity may be relevant. Under these conditions, an induction of ARAT is to be expected, and appropriate cell culture models should shed light on the relative relevance ...The median lipid droplet size in LRAT-/-HSCs (1080nm) is significantly smaller than in wild type HSCs (1618nm). This is a consequence of an altered lipid droplet size distribution with 50.5±9.0% small (≤700nm) lipid droplets in LRAT-/-HSCs and 25.6±1.4% large (1400-2100nm) lipid droplets in wild type HSC cells.Lecithin:retinol acyltransferase (LRAT) catalyzes the transfer of an acyl group from the sn-1 position of phosphatidylcholine to all-trans-retinol (vitamin A) and plays an essential role in the regeneration of visual chromophore as well as in the metabolism of vitamin A.
