This pathway catalogues RHOQ (also known as TC10) guanine nucleotide exchange factors (GEFs), GTPase activator proteins (GAPs), and RHOQ effectors. No GDP dissociation inhibitors (GDIs) have been shown to interact with RHOQ. Two GDIs, ARHGDIA (Michaelson et al. 2001; Murphy et al. 2001) and ARHGDIB (Zhang et al. 2009), were specifically shown not to interact with RHOQ. RHOQ, together with RHOJ (TCL), belongs to the CDC42 subfamily of RHO GTPases, with the three family members sharing 70-85% of homology (Donnelly et al. 2014; Shi et al. 2016). RHOQ is highly activated on exocytosing vesicles and recycling endosomes. RHOQ GTPase activity is necessary for fusion of vesicles with the plasma membrane (Donnelly et al. 2014). RHOQ is required for insulin-stimulated glucose uptake (Kanzaki and Pessin 2003; Saltiel and Pessin 2003) and is involved in insulin signaling in adipocytes (Satoh 2014). RHOQ is involved in neurite outgrowth and regulates membrane addition during axon formation (Gonzalez‐Billault et al. 2012).
