Bax inhibitor-1 (BI-1) interacts with Bax, neutralizing its proapoptotic activity. In this issue of Molecular Cell, Lisbona et al. (2009) show that BI-1 directly inhibits IRE1alpha, an essential mediator of the UPR, thereby facilitating crosstalk between apoptosis and ER stress pathways.
Bax抑制因子1(BI-1)与Bax相互作用,中和其促凋亡活性。在本期《分子细胞》杂志中,利斯博纳等人(2009年)表明,BI-1直接抑制IRE1α,即未折叠蛋白反应(UPR)的关键介质,从而促进凋亡与内质网应激途径之间的相互作用。
