CC -!- FUNCTION: Toxic type II ribosome-inactivating protein (RIP). Induces
CC apoptosis. Has cytotoxic activity against several human cancer cell
CC lines. Is less cytotoxic to normal human cells.
CC {ECO:0000269|PubMed:12963119, ECO:0000269|PubMed:15493877}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of the N-glycosidic bond at one specific
CC adenosine on the 28S rRNA.; EC=3.2.2.22;
CC -!- SUBUNIT: Disulfide-linked dimer of A and B chains.
CC {ECO:0000269|PubMed:12963119}.
CC -!- PTM: Glycosylated. {ECO:0000269|PubMed:12963119}.
CC -!- MISCELLANEOUS: The inhibitory concentration 50% (IC50) is 0.8 ng/ml for
CC transformed cells and 10 ng/ml for normal cells.
CC -!- SIMILARITY: Belongs to the ribosome-inactivating protein family. Type 2
CC RIP subfamily. {ECO:0000305}.
