RGS17 (Regulator of G-protein signaling 17) is a member of the RGS protein family, which plays a critical role in modulating G-protein-coupled receptor (GPCR) signaling pathways. As a GTPase-activating protein (GAP), RGS17 accelerates the hydrolysis of GTP bound to Gα subunits of heterotrimeric G-proteins, thereby terminating GPCR-mediated signaling. This regulatory function impacts diverse physiological processes, including neurotransmission, hormone secretion, and cell proliferation.
Structurally, RGS17 contains a conserved RGS domain responsible for Gα interaction, along with distinct N-terminal and C-terminal regions that may influence subcellular localization and protein-protein interactions. It is expressed in various tissues, with notable presence in the central nervous system, lungs, and testes, suggesting tissue-specific regulatory roles.
In pathological contexts, RGS17 has gained attention for its involvement in cancer progression. Overexpression of RGS17 has been observed in multiple malignancies, including lung cancer, prostate cancer, and neuroblastoma, where it promotes tumor growth, metastasis, and chemoresistance by dysregulating oncogenic pathways like Wnt/β-catenin and MAPK signaling. Its dual role as both a tumor suppressor and promoter in different cancer types highlights context-dependent functionality.
Recombinant RGS17 protein is typically produced using bacterial (E. coli) or mammalian expression systems, enabling studies of its biochemical properties, structural biology, and interaction networks. This engineered protein serves as a valuable tool for drug discovery targeting RGS17-associated diseases, particularly in developing small-molecule inhibitors for cancer therapy. Current research also explores its potential as a diagnostic biomarker and therapeutic target in neurological disorders, given its emerging links to addiction behaviors and neurodegenerative processes. The dynamic regulation and multifunctional nature of RGS17 continue to make it a compelling subject for both basic research and translational applications.
