RHOBTB1 (Rho-Related BTB Domain Containing 1): RHOBTB1 is a member of the Rho GTPase family, involved in regulating diverse cellular processes such as cytoskeletal organisation, cell cycle progression, and gene expression. Unlike typical Rho GTPases, it has a distinctive structure that suggests roles in vesicular trafficking and signal transduction. Dysregulation of RHOBTB1 has been linked to certain cancers, indicating its potential as a biomarker or therapeutic target.
