Activation of Bax and Bak by BH3-only molecules triggers mitochondrial apoptosis. In a recent issue of Molecular Cell, Fu et al. (2009) identify a constitutively active isoform of Bax, Baxbeta, whose activity is tightly controlled by the ubiquitin-proteasome system.
仅含BH3结构域的分子激活Bax和Bak会触发线粒体凋亡。在最近一期的《分子细胞》杂志上,傅等人(2009年)鉴定出一种组成型活性的Bax异构体,即Baxbeta,其活性受到泛素-蛋白酶体系统的严格调控。
