RHOD is an atypical RHO GTPase that possesses an elevated intrinsic guanine nucleotide exchange activity (Jaiswal, Fansa et al. 2013) and has never been shown to interact with any guanine nucleotide exchange factor (GEF), including DOCK11 (Ruiz-Lafuente et al. 2015), ITSN1 (Jaiswal et al. 2013), MCF2 (Jaiswal et al. 2013), MCF2L (Jaiswal et al. 2013), PREX1 (Jaiswal et al. 2013), TIAM1 (Jaiswal et al. 2013), TRIO (Jaiswal et al. 2013) and VAV2 (Jaiswal et al. 2013). As GTP is more abundant in cells than GDP (Traut 1994), RHOD is thought to be present in a constitutively active state (Jaiswal, Fansa et al. et al. 2013).
RHOD localization depends on its activation state - inactive RHOD is mainly cytosolic, while GTP-bound RHOD is found at the plasma membrane and at vesicle membranes (Blom et al. 2018).
