SREBP-1 and SREBP-2 (Sterol regulatory element-binding protein 1 and 2) are members of the basic-helix-loop-helix-leucine zipper (bHLH-ZIP) family of transcription factors and are involved in the regulation of cholesterol homeostasis. SREBP-1 and SREBP-2 are normally membrane bound at the ER and nuclear envelope, but in sterol-depleted cells, the membrane-bound precursors are cleaved to generate a soluble isoforms that translocate to the nucleus. These active forms, which include the bHLH-ZIP domain, activate transcription of genes involved in the uptake and synthesis of cholesterol. SREBP-1 antibody (mAb) (Clone IgG-2A4) was raised in a Mouse host. It has been validated for use in Chromatin Immunoprecipitation, Immunoprecipitation, Supershift and Western blot, it has been shown to react with Human samples.
