Abstract

A sterol regulatory element (SRE) binding protein (SREBP) which activates transcription from SREs, such as SRE-1 of the low density lipoprotein (LDL) receptor gene, is disclosed, as are DNA segments encoding SREBPs such as an SREBP-1 or SREBP-2. Also described are methods for using SREBP to promote SRE-mediated transcription and LDL receptor production in the presence of sterols, and screening assay for the identification of further agents with such properties. The SREBP and other agents may be used to reduce plasma cholesterol levels and to treat various medical problems associated with hypercholesterolemia.
