Exosite-mediated targeting of GSDMB by dimeric granzyme A in lymphocyte pyroptotic killing
In cellular immunity, cytotoxic lymphocytes-derived granzyme A (GZMA) targets the pore-forming protein GSDMB in target cells to confer pyroptotic killing, but how GZMA specifically recognizes and cleaves GSDMB is unknown. Zhong et al. demonstrate that …
