    Sterol regulatory element 1 (SRE-1), a decamer (5'-ATC-ACCCCAC-3') flanking the low density lipoprotein (LDL) receptor gene, activates transcription in sterol-depleted cells and is silenced by sterols. We report the cDNA cloning of human SREBP-1, a protein that binds SRE-1, activates transcription, and thereby mediates the final regulatory step in LDL metabolism. SREBP-1 contains a basic-helix-loop-helix-leucine zipper (bHLH-ZIP) motif, but it differs from other bHLH-ZIP proteins in its larger size (1147 amino acids) and target sequence. Instead of an inverted repeat (CANNTG), the target for all known bHLH-ZIP proteins, SRE-1 contains a direct repeat of CAC. Overexpression of SREBP-1 activates transcription of reporter genes containing SRE-1 in the absence (15-fold) and presence (90-fold) of sterols, abolishing sterol regulation. We suggest that SREBP-1 is regulated by an unknown factor that is overwhelmed when SREBP-1 is overexpressed. Understanding the regulation of SREBP-1 may be crucial for understanding the control of plasma cholesterol in humans.

      Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.

    • Gene (OMIM)

      Gene records associated with Online Mendelian Inheritance in Man (OMIM) records that cite the current articles in their reference lists.

    • HomoloGene

      HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.

    • Nucleotide

      Primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.

    • Nucleotide (RefSeq)
