Microbial GAIN domains undergo autoproteolysis and enable release of diverse cell surface associated proteins https://www.biorxiv.org/content/10.64898/2026.05.12.724683v1
My latest work! We found that the autoproteolytic GAIN domain which mediates force responsive signaling in adhesion GPCRs is not unique to eukaryotes. The microbial counterparts anchor diverse adhesion, enzymatic, and toxin domains to the cell surface, enabling release by likely mechanical stimuli.
Ph.D. finished! So many people to thank (pictured) but especially B. subtilis (& S. aureus & B. anthracis) (not pictured)
