RHOBTB1, like other members of RHOBTB family, RHOBTB2 and RHOBTB3, binds to CUL3 (cullin-3), a core component of the BTB-CUL3-RBX2 E3 ubiquitin ligase complex (Berthold et al. 2008). RHOBTB1 binds to ROCK1 and ROCK2, and ROCK-mediated phosphorylation of RHOBTB1 may regulate its association with CUL3 (Haga et al. 2019). RHOBTB1 has been proposed as a substrate adaptor for PDE5, targeting it to CUL3 complexes for ubiquitination (Mukohda et al. 2019).
