概述| 货号 | 557037 |
| 描述 | SREBP-1 and -2 (sterol-regulatory element binding proteins-1 and -2) are transcription factors which participate in the control of cholesterol homeostasis. SREBP proteins, which are attached to the endoplasmic reticulum and nuclear envelope, are proteolytically cleaved and thus activated in response to conditions of low cellular sterol. Upon activation of SREBP-1 or -2, a ~480-500 amino acid, N-terminal cleavage fragment of these proteins enters the nucleus and activates transcription of enzymes and other proteins required for cholesterol synthesis. Proteases which cleave SREBPs have been identified and include SCA (SREBP-cleavage activity), as well as caspase-3, a key regulator of apoptotic pathways. SREBP proteins containing point mutations at caspase-3 cleavage sites (Asp460 in SREBP-1 and Asp468 in SREBP-2) do not become cleaved following induction of apoptosis, suggesting that SREBPs may play some role in apoptotic processes. However, sterol-regulated vs. apoptosis-associated cleavage of SREBP proteins appears to be independently regulated. On SDS-PAGE, sterol-regulated cleavage fragments of SREBP proteins migrate more slowly (i.e., higher molecular weight) than do staurosporin-induced fragments. In addition, staurosporin-induced SREBP cleavage products may appear as a doublet, with the upper band representing a phosphorylated form of SREBP. On SDS-PAGE, full length, precursor forms of SREBP-1 and -2 migrate at ~125 kD, while proteolytic cleavage fragments may be observed as a cluster of bands between 60 - 70 kDa. The IgG-1C6 antibody recognizes human SREBP-2. The antibody recognizes the C-terminal of human SREBP-2. A fusion protein containing C-terminal amino acids 833-1141 of human SREBP-2, was used as immunogen. The antibody recognizes both the 125 kDa precursor and the 60-70 kDa COOH-terminal cleaved forms of SREBP-2. |
