Prior partial cleavage of the immunotoxin with furin was shown to overcome this resistance in Daudi cells [, It has also been observed that knockdown of the insulin receptor increases cleavage of SS1P by furin through an unknown mechanism and correspondingly increases SS1P cytotoxicity by increasing the amount of processed toxin that can reach the cytosol and inactivate EF2 [, To determine if other tyrosine kinases might also regulate immunotoxin activity, a separate study was performed to follow up on this result. It is a single-chain polypeptide (molecular weight, 71,000) with A and B fragments that mediate enzymatic and cell-binding functions, respectively. This item is part of a JSTOR Collection.
