| Outline of Final Research Achievements |
In this study, EPS8L3 was identified as a novel regulator of YAP that controls its stability and activity independently of the Hippo pathway. EPS8L3 was shown to physically interact with YAP and protect it from ubiquitination and proteasomal degradation. Moreover, EPS8L3 expression correlated with YAP levels and prognosis in human cancers.
These findings suggest that targeting the EPS8L3-YAP axis could potentially serve as a therapeutic strategy for YAP-dependent cancers and provide new insights into YAP regulation.

| Academic Significance and Societal Importance of the Research Achievements |
The Hippo signaling pathway and its key effector, Yes-associated protein (YAP), play crucial roles in regulating organ size, tissue homeostasis, and cell proliferation. Dysregulation of this pathway can lead to the development and progression of various types of cancer.
