WebJun 20, 2024 · This pattern is very much reminiscent of the T315I gatekeeper mutation in the fused BCR-ABL . Current free energy models are not able to precisely model the effects of double mutants such as T474M and E513G. Hence, the T474 residue is a gatekeeper that controls BTK binding to covalent and noncovalent inhibitors. WebThe BCR-ABL T315I mutation compromises survival in chronic phase chronic myelogenous leukemia patients resistant to tyrosine kinase inhibitors, in a matched pair analysis May …

WebJan 10, 2014 · The T315I mutation is of special interest as it continues to be an obstacle to the use of TKIs. In this review, we cover the clinical efficacy data of the approved agents … WebNov 13, 2024 · The “gatekeeper” mutation T315I confers resistance against all approved TKIs, with the only exception of Ponatinib, a multi-target kinase inhibitor. CML and Ph+ … WebApr 25, 2024 · Likewise, modeling studies with ABL predicted that the gatekeeper mutant, T315I, will block pluripotin binding (Figure 3O). Accordingly, the expression of BCR-ABL T315I conferred resistance to pluripotin (Figure 3P). Altogether, these data clearly demonstrate that pluripotin is a type II inhibitor of FLT3, ABL, and Jak2. reading report on the darkest hour
