SCAP(SREBP裂解激活蛋白)是一种位于内质网膜上的重要调控蛋白,属于固醇调节元件结合蛋白(SREBP)通路的核心组分。它的主要功能是作为胆固醇和脂质代谢的关键传感器,通过调控SREBP的裂解和活化来影响细胞内胆固醇和脂肪酸的合成。SCAP通过与SREBP形成复合物,感知细胞内固醇水平的变化。当固醇水平低时,SCAP-SREBP复合物从内质网转运至高尔基体,SREBP被蛋白酶裂解后释放其转录因子结构域进入细胞核,激活下游脂质合成相关基因(如HMGCR、LDLR等)的表达。SCAP的固醇敏感结构域(SSD)是其感知固醇的核心区域,突变(如D443N)可能导致固醇感应功能丧失,使SREBP持续活化,引发家族性高胆固醇血症等代谢疾病。SCAP过表达会增强SREBP通路的活性,促进脂质过度积累,与肥胖、非酒精性脂肪肝和动脉粥样硬化密切相关;而降低SCAP表达则抑制脂质合成,可能改善代谢紊乱但可能影响膜形成等生理过程。SCAP属于WD40重复蛋白家族,该家族成员通常含有β-螺旋桨结构的WD40重复序列,介导蛋白质相互作用。SCAP通过其WD40结构域与Insig蛋白结合实现固醇依赖性调控。该基因在肝脏、脂肪组织和肾上腺等高代谢活性组织中表达丰富,其功能紊乱直接影响心血管健康和能量代谢平衡。

This gene encodes a protein with a sterol sensing domain (SSD) and seven WD domains. In the presence of cholesterol, this protein binds to sterol regulatory element binding proteins (SREBPs) and mediates their transport from the ER to the Golgi. The SREBPs are then proteolytically cleaved and regulate sterol biosynthesis. [provided by RefSeq, Jul 2008]

该基因编码具有固醇检测域(SSD)和七个WD域的蛋白质。在胆固醇存在下,这种蛋白结合固醇调节元件结合蛋白(SREBPs)和从ER到高尔基体介导它们的传输。该SREBPs然后蛋白水解切割和规范甾醇生物合成。 [由RefSeq的,2008年7月提供]
