Gα_q controls organ size and developmental timing in Drosophila.

ABSTRACT: The G protein alpha subunit, Gαq, transduces extracellular signals from G-protein-coupled receptors (GPCRs) into the cell, playing essential roles in developmental processes such as organ size control, wound healing, and disease. Hyperactivating mutations in the Gαq are associated with Sturge-Weber syndrome and uveal melanoma, and thus, it serves as an important candidate drug target. However, the downstream mechanisms of Gαq signaling remain poorly defined, creating a bottleneck for designing more effective and targeted therapeutics. Here, we used Drosophila melanogaster wing discs to investigate the cellular and transcriptional consequences of Gαq dysregulation in a model epithelial system. We found that overexpression of Gαq in the wing discs reduces adult wing size and induces systemic
