WebThe sodium-dependent multivitamin transporter (SMVT) is essential for mediating and regulating biotin entry into mammalian cells. In cells, holocarboxylase synthetase (HCS) mediates covalent binding of biotin to histones; biotinylation of lysine-12 in histone H4 (K12BioH4) causes gene repression. Here we propose a novel role for HCS in sensing … WebCorrespondingly, supplementation of cells with pharmacological doses of biotin increases biotinylation of histones, decreasing expression of biotin transporters. This would be an intriguing mechanism by which the cellular concentration of biotin directly controls the expression of biotin transporters by regulating chromatin remodeling events.
