EXOC2

该基因编码的蛋白质是胞外囊复合物的一个组成部分,胞外囊复合物是一种多蛋白复合物,是胞外囊泡极化靶向细胞膜上特定对接位点所必需的虽然在酵母中表现最好,但在高等真核生物中,外囊复合体的组成蛋白和功能已被证明是高度保守的包括这种蛋白在内,至少有八种胞外复合物成分被发现与肌动蛋白细胞骨架重塑和囊泡转运机制相互作用。这种相互作用已被证明介导成纤维细胞中丝状体的形成。该蛋白已被证明与GTPases的Ral亚家族相互作用,从而通过将囊泡系在质膜上介导胞吐选择性剪接导致多个转录变体[由RefSeq提供,2012年7月]
The protein encoded by this gene is a component of the exocyst complex, a multi-protein complex essential for the polarized targeting of exocytic vesicles to specific docking sites on the plasma membrane. Though best characterized in yeast, the component proteins and the functions of the exocyst complex have been demonstrated to be highly conserved in higher eukaryotes. At least eight components of the exocyst complex, including this protein, are found to interact with the actin cytoskeletal remodeling and vesicle transport machinery. This interaction has been shown to mediate filopodia formation in fibroblasts. This protein has been shown to interact with the Ral subfamily of GTPases and thereby mediate exocytosis by tethering vesicles to the plasma membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]
