UCH-L1 regulates eye differentiation-related genes and modulates EGFR signalling in <i>Drosophila melanogaster</i>.

ABSTRACT: UCH-L1 (Ubiquitin Carboxyl-terminal Hydrolase - L1) is a protein that plays a critical role in the ubiquitin-proteasome system. Previous studies have demonstrated a link between UCH-L1 and various diseases, including neurodegenerative disorders, diabetes, and cancer. However, the role of UCH-L1 in development remains unclear. To investigate the functions of UCH-L1 in a living organism, taking advantage of the Drosophila model, and to explore the correlation between Drosophila UCH (dUCH) and human UCH-L1, we established a GAL4/UAS-targeted expression system to examine the effect of dUCH on Drosophila eye development. We found that knockdown of dUCH resulted in a rough eye phenotype associated with the MAPK pathway. In this study, for the first time, we revealed that loss of dU
