The mouse I105N/human I104N mutation, which has been shown to prevent macrophage pyroptosis, attenuated both cell killing by p30 in a 293T transient overexpression system and membrane permeabilization in vitro, suggesting that the mutants are actually hypomorphs, but must be above certain concentration to exhibit activity. Graphs show mean s.d. GSDMA 1246aa, but not 1214aa possesses pyroptosis-inducing activity. GSDMA acts as both a sensor and substrate of GAS SpeB and as an effector to trigger pyroptosis, adding a simple one-molecule mechanism for host recognition and control of virulence of a dangerous microbial pathogen. Immun. Proceedings of the National Academy of Sciences of the United States of America. Streptolysins are the primary inflammasome activators in macrophages during Streptococcus pyogenes infection. 3 |. After recognizing invasive bacteria or other danger signals, innate immune receptors form large supramolecular complexes called inflammasomes that activate inflammatory caspases, cleave GSDMD and release the N-terminus.

SpeB is a cysteine protease and can directly cleave both human PubMed Results show that SCP can display an important level of endopeptidase activity and the substrate specificity outlined in this work further supports the similarity between SCP and the cysteine proteases of the papain family. Here we show that the GAS cysteine protease SpeB virulence factor triggers keratinocyte pyroptosis by cleaving GSDMA after Gln246, unleashing an active N-terminal fragment that triggers pyroptosis.
