一般說明
3-羟基-3-甲基戊二酰辅酶A还原酶（EC 1.1.1.34；UniProt P00347；也称HMG-CoA还原酶）由灰仓鼠（中国仓鼠）的HMGCR基因（基因ID 100756363）编码。HMG-CoA还原酶可催化HMG-CoA转化为甲羟戊酸，是甲羟戊酸-异戊二烯类化合物生物合成（MIB）途径的限制性酶，负责生成胆固醇和其他异戊二烯类化合物，以及蛋白质异戊二烯化所需的法尼基焦磷酸盐（FPP）。HMG-CoA还原酶受到低密度脂蛋白（LDL）通过LDL受体内化和降解产生的胆固醇以及氧化胆固醇类物质的抑制。HMG-CoA还原酶的竞争性抑制剂诱导肝脏中LDL受体的表达，进而增加血浆LDL的分解代谢，降低血浆胆固醇的浓度。HMG-CoA还原酶是一种多跨膜内质网蛋白，具有N端甾醇敏感结构域（SSD；a.a.61-218）和C端催化结构域（a.a.450-888），其活性在SSD与胆固醇结合时受到抑制。许多研究表明HMG-CoA还原酶和甲羟戊酸途径参与肿瘤发生。
特異性
克隆IgG-A9靶向HMC-CoA还原酶催化结构域内的表位（a.a. 450 887）。
免疫原
Membrane preapration from compactin-adapted CHO cells (Liscum, L., et al. (1983).J. Biol. Chem. 258(13) 8450-8455).
應用
可使用这种小鼠HMG-CoA还原酶单克隆抗体（克隆IgG-A9，货号MABS1233）检测HMG CoA还原酶，该抗体经验证可用于免疫细胞化学、免疫沉淀和蛋白质印迹。

Western Blotting Analysis: A 1:100 dilution from a representative lot detected in 15 µg of membrane extract from CHO7 cells treated overnight with 0.01 mM compactin (Courtesy of Linda Donnelly, Department of Molecular Genetics, UT Southwestern Medical Center, Dallas, TX, USA).
Immunocytochemistry Analysis: A representative lot detected HMG CoA reductase-positive ER membrane structures by indirect immunofluorescence staining of paraformaldehyde-fixed, 0.1% Triton X-100-permeabilized CHO-K1 cells cultured with compactin, mevalonate, and MG-132, in the presence or absence of 25-hydroxycholesterol (25-HC) (Hartman, I.Z., et al. (2010). J. Biol. Chem. 285(25):19288-19298).
Immunoprecipitation Analysis: A representative lot immunodepleted HMC-CoA reductase activity from compactin-adapted CHO cell (UT-1) extract (Liscum, L., et al. (1983). J. Biol. Chem. 258(13) 8450-8455).
Western Blotting Analysis: A representative lot detected 25-hydroxycholesterol (25-HC) treatment-induced HMC-CoA reductase dislocation from ER membrane to the cytosol and lipid droplet in CHO-K1 cells cultured with lipoprotein-deficient serum in the presence of compactin, MG-132, with or without mevalonate. Cellular VCP knockdown prevented sterol-induced HMC-CoA reductase cytosolic, but not lipid droplet, translocation (Hartman, I.Z., et al. (2010). J. Biol. Chem. 285(25):19288-19298).
Western Blotting Analysis: A representative lot detected 25-hydroxycholesterol (25-HC) treatment-induced ubiquitination of HMC-CoA reductase in SV-589 human fibroblasts cultured with compactin and mevalonate in the presence of proteasome inhibitor MG-132. Cellular knockdown of gp78A, but not gp78B or Hrd1, reduced 25-HC-induced HMC-CoA reductase ubiquitination (Song, B.L., et al. (2005). Mol. Cell. 19(6):829-840).
Western Blotting Analysis: A representative lot detected 25-hydroxycholesterol (25-HC) treatment-induced degradation of HMC-CoA reductase in SV-589 human fibroblasts cultured with compactin and mevalonate. Cellular knockdown of gp78A, VCP, or Insig-1/-2 suppressed sterol-induced HMC-CoA reductase degradation (Song, B.L., et al. (2005). Mol. Cell. 19(6):829-840).
Western Blotting Analysis: A representative lot detected HMC-CoA reductase in both membrane and nuclear fractions from HEK-293S cells cultured with compactin and mevalonate. Additional treatment with 25-hydroxycholesterol (25-HC) resulted in HMC-CoA reductase degradation (Sever, N., et al. (2003). Mol. Cell. 11(1):25-33).
Western Blotting Analysis: A representative lot detected an upregulated HMC-CoA reductase expression in compactin-adapted CHO cells (UT-1), as well as a loss of HMC-CoA reductase expression in UT-1 cells cultured in the presence of LDL (Liscum, L., et al. (1983). J. Biol. Chem. 258(13) 8450-8455).
Western Blotting Analysis: A representative lot detected a greater HMC-CoA reductase upregulation in liver microsome preparation from rats on diet supplemented with cholestyramine and mevinolin than with cholestyramine alone, while supplementation with cholesterol in addition to cholestyramine and mevinolin downregulated liver HMC-CoA reductase (Liscum, L., et al. (1983). J. Biol. Chem. 258(13) 8450-8455).
