Oxysterol-binding protein (IPR000648)

Short name: Oxysterol-bd

Overlapping homologous superfamilies

Family relationships



A number of eukaryotic proteins that seem to be involved with sterol synthesis and/or its regulation have been found [PMID: 8017104] to be evolutionary related. These include mammalian oxysterol-binding protein (OSBP), a protein of about 800 amino-acid residues that binds a variety of oxysterols (oxygenated derivatives of cholesterol); yeast OSH1, a protein of 859 residues that also plays a role in ergosterol synthesis; yeast proteins HES1 and KES1, highly related proteins of 434 residues that seem to play a role in ergosterol synthesis; and yeast hypothetical proteins YHR001w, YHR073w and YKR003w.
