Antiapoptotic Bcl-2 proteins on mitochondria inhibit prodeath proteins, such as Bax, which are found primarily in the cytosol. In this issue, Edlich et al., (2011) show that Bax and Bcl-xL interact on the mitochondrial surface and then retrotranslocate to the cytosol, effectively preventing Bax-induced permeabilization of mitochondria.
线粒体上的抗细胞凋亡 Bcl-2 蛋白抑制主要存在于细胞质中的促死亡蛋白,如 Bax。在本期杂志中,Edlich 等人(2011)表明 Bax 和 Bcl-xL 在线粒体表面相互作用,然后逆行转运到细胞质中,有效地防止 Bax 诱导的线粒体通透性增加。
