Targeted degradation of endogenous YAP by nanobody bioPROTAC inhibits tumor progression.

ABSTRACT: Yes-associated protein (YAP), a key effector of the Hippo pathway, regulates gene expression and promotes tumorigenesis. YAP is conventionally considered "undruggable", however, targeted protein degradation offers a promising approach to address the challenges associated with targeting this oncogenic protein. In this study, through naïve nanobody phage library screening, we identify multiple nanobodies against human YAP with high affinity and specificity. The YAP nanobody is then fused to the RING domain of RNF4, creating a bio-Proteolysis-Targeting Chimera (bioPROTAC) molecule capable of selectively targeting endogenous YAP for ubiquitin-mediated degradation. Notably, the constructed YAP bioPROTAC demonstrates significant YAP degradation and anticancer efficacy in various YAP-dependent ca
