Exosite-mediated targeting of GSDMB by dimeric granzyme A in lymphocyte pyroptotic killing

{{output}}
In cellular immunity, cytotoxic lymphocytes employ granzyme A (GZMA) to cleave and activate the pore-forming protein gasdermin B (GSDMB) for the pyroptotic killing of target cells. How GZMA recognizes and cleaves GSDMB is unknown. Here, we show that human GZMA... ...
