RHOBTB2. a member of the Rho GTPase family, is distinguished by its unique structural organization, combining a conserved GTP-binding domain with an extended C-terminal region containing two tandem BTB (Broad-Complex, Tramtrack, Bric-a-brac) domains. Unlike typical Rho GTPases that regulate cytoskeletal dynamics, RHOBTB2 primarily functions in intracellular trafficking, protein degradation, and cell cycle regulation. It acts as a substrate adaptor for the Cullin 3 (Cul3) ubiquitin ligase complex, facilitating the ubiquitination and proteasomal degradation of target proteins. This interaction is critical for maintaining cellular homeostasis, particularly in response to stress signals.
RHOBTB2 is ubiquitously expressed, with notable roles in neuronal and cardiovascular systems. Research links its dysfunction to various diseases, including cancers, where it often exhibits tumor-suppressive activity by inhibiting proliferation and promoting apoptosis. For instance, RHOBTB2 downregulation is observed in colorectal and breast cancers, correlating with poor prognosis. In neurodegenerative contexts, it aids in clearing misfolded proteins, implicating it in conditions like Alzheimer's disease. Additionally, RHOBTB2 mutations are associated with developmental delays and epilepsy, highlighting its importance in neurodevelopment.
Despite its diverse roles, RHOBTB2's precise molecular mechanisms remain partially characterized, warranting further exploration. Its dual regulatory capacity—bridging small GTPase signaling and ubiquitin-mediated proteostasis—positions it as a promising therapeutic target for diseases linked to protein misfolding or dysregulated proliferation.
