3SA2_NAJOX This three-finger cytotoxin is a basic protein that interacts and penetrates into the cell membrane, with the tips of all the three loops. Cytotoxins which have a Pro-30 (P-type) interacts with membrane stronger that those which have a 'Ser-28' (S-type). CTII interacts with membrane stronger than CTI.[1][2][3]
