In order to activate transcription, the NH2-terminal domain of the SREBP must be released from the membrane so that it can enter the nucleus. This release has been studied most extensively for one of the SREBPs, namely, SREBP-2. However, the mechanism appears to be similar for the other SREBPs (SREBP-1a and -1c) (1). Release of the NH2-terminal domain is accomplished by a two-step proteolytic event that is regulated by sterols (3). In sterol-depleted mammalian cells, this proteolysis is initiated by the Site-1 protease (S1P), which cleaves human SREBP-2 between the Leu522-Ser523 bond in the sequence RSVL S (4). This cleavage requires formation of a complex between SREBP and SCAP, a polytopic membrane protein of the ER, and it is prevented when this complex is disrupted |
