Abstract
Targeted membrane protein degradation (TMPD) offers significant therapeutic potential by enabling the removal of harmful membrane-anchored proteins and facilitating detailed studies of complex biological pathways. However, existing TMPD methodologies face challenges such as complex molecular architectures, scarce availability, and cumbersome construction requirements. To address these issues, this study presents a highly efficient TMPD system (TMPDS) that integrates an optimized bivalent aptamer glue with a potent protein transport shuttle. Utilizing this approach, we successfully degraded both the highly expressed protein tyrosine kinase 7 in CCRF-CEM cells and the poorly expressed PTK7 in MV-411 cells. This system represents significant advancement in the field of molecular medicine, offering a new avenue for targeted therapeutic interventions and the exploration of cellular mechanisms.
