靶點詳情

功能：

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 (Probable). LRAT plays a critical role in vision (Probable). 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 (Probable). Required for the survival of cone photoreceptors and correct rod photoreceptor cell morphology.

1. The genetic analysis performed on our proband showed a novel homozygous mutation on codon 119 of lecithin-cholesterol acyltransferase gene that causes the substitution of glycine by aspartate PMID: 28942093
2. instability of LRAT(E14L) did not abrogate the production of the visual chromophore in a cell-based assay. Instead, expression of LRAT(E14L) led to a rapid increase in cellular levels of retinoic acid upon retinoid supplementation. PMID: 28758396
3. LRAT hypermethylation was associated with decreased mRNA levels in colorectal cancer clinical specimens. PMID: 25260806
4. lecithin retinol acyltransferase affects all-trans retinoic acid levels and has a role in retinoid sensitivity in malignant melanoma cells. PMID: 25236354
5. These findings reveal structural adaptation that facilitates selective catalysis and mechanism responsible for diverse substrate specificity within the LRAT-like enzyme family PMID: 25383759
6. high LRAT expression in melanoma might be important in removing retinol as substrate for RA production, thereby inducing signalling pathways leading to dedifferentiation, proliferation and anti-apoptosis PMID: 24433184
7. Functional hepatic stellate cells coexpressing both LRAT and CRBP-1, that continue to maintain the ability to store vitamin A, contribute in part to the development of portal and parenchymal fibrogenesis in patients with viral hepatitis. PMID: 23890161
8. Lecithin-retinol acyltransferase is a thermostable and highly active enzyme with a likely mode of interfacial activation. PMID: 24613493
9. A genetic defect was identified in LRAT as a novel cause of retinitis punctata albescens. PMID: 22559933
10. Data show that acyl-modified forms of HRAS-like tumor suppressors HRASLS2 and HRASLS3 mimicking lipolytic activity of lecithin retinol acyltransferase LRAT. PMID: 22605381
11. LRAT mutations cause a severe, early childhood onset, progressive retinal dystrophy. PMID: 22570351
12. This study showed that malignant melanoma cells are able to esterify all-trans retinol and subsequently isomerize all-trans retinyl esters (RE) into 11-cis retinol, whereas their benign counterparts-melanocytes are not able to catalyze these reactions. PMID: 21465477
13. Data show that overexpression of human LRAT specifically in mice oral basal epithelial cells makes these cells more sensitive to carcinogen induced tumorigenesis. PMID: 19471114
14. LRAT expression is higher in renal tumors with an indolent biological behavior PMID: 14581364
15. Conserved residues Cys-161 and His-60 form the essential catalytic dyad of LRAT that represents a novel thiol protease motif, which functions in an acyltransferase reaction. PMID: 14596594
16. LRAT has a role in preventing progression of invasive bladder cancer PMID: 15161698
17. Results provide evidence that multiple LRAT mRNA transcripts, which are expressed in a tissue-specific manner, may result from differential splicing of the 5'UTR region and the use of multiple polyadenylation signals in the 3'UTR. PMID: 15474300
18. LRAT has a role in retinoid absorption and storage PMID: 16115871
19. These experiments are consistent with an expanded role for LRAT function as a protein palmitoyl transferase. PMID: 16939223
20. The phenotype of patients with mutations in LRAT is similar to that of patients with mutations in RPE65, suggesting the need to systematically screen both genes in case of typical phenotype. PMID: 17011878
21. LRAT mutations are likely a rare cause of Leber congenital amaurosis among patients from North America. PMID: 17438524
22. Lecithin: retinol acyltransferase protein is distributed in both hepatic stellate cells and endothelial cells of normal rodent and human liver. PMID: 18544127
23. transcriptional regulation is aberrant in human prostate cancer and involves GATA transcription factors in normal prostate epithelial cells PMID: 18652909
24. proximal region together with basal transcription factors may be sufficient to drive Lrat expression. PMID: 19665987
