“…These contradictory findings show that RhoB's roles in cancer are highly contextual and cell-type specific. In the context of tumorigenesis vs tumor development and severity, numerous findings implied that RhoB performs two separate and opposing functions [3,[20][21][22][23].…”

Background: An indispensable member of the Rho family, RhoB is an isoprenylated small GTPases that modulate the cellular cytoskeletal organization. While DNA gets damaged, it takes part in the neoplastic apoptotic mechanism. In this study, we evaluated the structure of Rho-related GTP-binding protein RhoB due to the unavailability of 3D structure in the protein data bank database. Results: The expected pI value of RhoB was 5.10 (acidic). The target–template alignment was computed using the GMQE value meanwhile 6hxu.1.A from Homo sapiens was selected as the template structure. The Swiss model was exploited to complete the model construction task. The structural compatibility and stability were revealed after a 100ns molecular dynamics simulation using GROMACA employing the OPLS-AA force field. Based on their fluctuating activity and their location between 100 and 110 and 140 and 150, PCA analysis discovered relevant residues. Conclusion: By providing an insight into the biophysical phenomenon of Rho-related GTP-binding protein RhoB inhibitors, this study will assist future investigations addressing the relationship between gene mutation and abnormalities produced by protein Rho-related GTP-binding protein RhoB in apoptotic events.
