Gpr146, a G protein-coupled receptor (GPCR) primarily located in the plasma membrane, is a multifaceted player in cellular processes, contributing significantly to diverse physiological functions. Predicted to enable microtubule binding activity and microtubule motor activity, Gpr146 participates in critical processes such as the establishment of cell polarity, positive regulation of cell-cell adhesion, and ureteric bud invasion. The gene exhibits expression in various structures, including the alimentary system, central nervous system, genitourinary system, hindlimb interdigital region, and sensory organs. Its orthologous relationship with the human GPR146 emphasizes its evolutionary conservation and potential importance across species.

In the context of Gpr146's inhibition, a range of chemical compounds target its signaling pathways, influencing the receptor's functional roles. These mechanisms of inhibition include interference with the Rho/ROCK signaling pathway, modulation of TGF-β signaling, disruption of Gαi protein-mediated GPCR signaling, and inhibition of crucial cascades such as MAPK/ERK and PI3K/Akt pathways. Additionally, inhibitors targeting Wnt and Hedgehog pathways showcase the interconnectedness of Gpr146 with broader cellular signaling networks. The diverse chemical interventions underscore the intricate regulatory role Gpr146 plays in cellular processes, and the varying mechanisms of inhibition highlight the complexity of modulating GPCRs within intricate signaling networks. It becomes evident that Gpr146's influence is not confined to a singular pathway but is intricately woven into a network of interconnected signaling cascades, reflecting its importance in maintaining cellular homeostasis and contributing to developmental processes. Understanding the functional significance of Gpr146 and its modulation provides insights into the dynamic nature of GPCR signaling in cellular physiology. The intricacies of Gpr146's involvement in microtubule dynamics, cell adhesion, and organ development underscore its relevance in fundamental biological processes. The chemical interventions explored in inhibition studies illuminate the potential for targeted manipulation of Gpr146 signaling to dissect and understand its precise role in cellular contexts.
