RHOB explained

Ras homolog gene family, member B, also known as RHOB, is a protein which in humans is encoded by the RHOB gene.^{[1] [2]}

RHOB is a member of the Rho GTP-binding protein family.^[3]

Interactions

RHOB has been shown to interact with CIT,^[4] ARHGEF3,^[5] ARHGDIG^[6] and RHPN2.^[7]
