Nr1h3 | Oxysterols receptor LXR-alpha; Nuclear receptor that exhibits a ligand-dependent transcriptional activation activity. Interaction with retinoic acid receptor (RXR) shifts RXR from its role as a silent DNA-binding partner to an active ligand- binding subunit in mediating retinoid responses through target genes defined by LXRES. LXRES are DR4-type response elements characterized by direct repeats of two similar hexanuclotide half-sites spaced by four nucleotides. Plays an important role in the regulation of cholesterol homeostasis, regulating cholesterol uptake through MYLIP-dependent ub [...] (445 aa) | ||||
Rdh11 | Retinol dehydrogenase 11; Retinol dehydrogenase with a clear preference for NADP. Displays high activity towards 9- cis, 11-cis and all-trans-retinol, and to a lesser extent on 13-cis- retinol (By similarity). Exhibits also reductive activity towards toxic lipid peroxidation products such as medium-chain aldehydes trans-2-nonenal, nonanal, and cis-6-nonenal. Has no dehydrogenase activity towards steroid. Seems to be required for homeostasis of retinol in liver and testis ; Belongs to the short-chain dehydrogenases/reductases (SDR) family. (316 aa) |
