In its GTP bound active form, plasma membrane associated RHOB (or constitutively active RHOB mutant in the high throughput study by Bagci et al. 2020) binds to the following effectors at the plasma membrane:
CIT (Madaule et al. 1995; Bagci et al. 2020) and its neuron specific isoform CIT 3 (Di Cunto et al. 1998)
DAAM1 (Higashi et al. 2008)
PKN1 (Hutchinson et al. 2013)
PKN2 (Hutchinson et al. 2013; Bagci et al. 2020)
PKN3 (Hutchinson et al. 2013)

ROCK2 (Leung et al. 1996; Bagci et al. 2020)
RTKN (Reid et al. 1996)
