In theory, on entry into endosome of tumor cells immunoGrB protein releases C-terminal PE Ⅱ-GrBa into cytosol as a result of auto-cleavage of peptide bond between Arg279 and Gly280. Two kinds of PE translocating peptides covering 253-364 aa and 253-358 aa were compared for their endosome-disruptive function.
