Pore-forming activity-caged macrolittin 70
WebFeb 18, 2024 · Pore-forming proteins (PFPs) exist in virtually all domains of life, and by disrupting cellular membranes, depending on the pore size, they cause ion dis-balance, small substances, or even protein efflux/influx, influencing cell’s signaling routes and fate. Such pore-forming proteins exist from bacteria to viruses and also shape host defense … Webpore-forming independent properties have been reported. Alter-natively, CDCs might have the capacity to transiently permeabi-lize membranes at low concentrations, through structures that differ from the large oligomeric pores. Such a differential behavior highlights the importance of monitoring changes in ion composition and utilizing mutants ...
