Plays a key role in cell positioning and movement in lymphoid tissues: 25-hydroxycholesterol is an intermediate in biosynthesis of 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC), an oxysterol that acts as a ligand for the G protein-coupled receptor GPR183/EBI2, a chemotactic receptor for a number of lymphoid cells. May play an important role in regulating lipid metabolism by synthesizing a corepressor that blocks sterol regulatory element binding protein (SREBP) processing. In testis, production of 25-hydroxycholesterol by macrophages may play a role in Leydig cell differentiation. {ECO:0000250|UniProtKB:Q9Z0F5, ECO:0000269|PubMed:9852097}. |FA hydroxylase| |cholesterol 25-hydroxylase activity| |C-4 methylsterol oxidase activity| |B cell chemotaxis| |bile acid biosynthetic process| |steroid hydroxylase activity| |bile acid metabolic process| |lymphocyte chemotaxis| |sterol biosynthetic process| |lymphocyte migration| |cholesterol metabolic process| |steroid biosynthetic process| |secondary alcohol metabolic process| |iron ion binding| |sterol metabolic process| |leukocyte chemotaxis| |monocarboxylic acid biosynthetic process| |organic hydroxy compound biosynthetic process| |cell chemotaxis| |steroid metabolic process| |carboxylic acid biosynthetic process| |organic acid biosynthetic process| |alcohol metabolic process| |leukocyte migration| |organic hydroxy compound metabolic process| |monocarboxylic acid metabolic process| |chemotaxis| |taxis| |lipid biosynthetic process| |small molecule biosynthetic process| |carboxylic acid metabolic process| |endoplasmic reticulum membrane| |cell migration| |oxidation-reduction process| |oxoacid metabolic process| |organic acid metabolic process| |localization of cell| |cell motility| |lipid metabolic process| |organic cyclic compound biosynthetic process| |locomotion| |movement of cell or subcellular component| |small molecule metabolic process| \\ === CRISPR Data === No hits were found.
