The members of the R7 family of RGS proteins [1] are more complex structures than the R4 family and are closely related to the C. elegans homologues EGL-10 and EAT-16 that were identified in the early stage of RGS protein research [2,5]. Apart from the RGS domain, several additional domains are present in these proteins that mediate protein-protein interactions, sub-cellular localization and protein stability. All R7 family members form obligatory dimers with Gβ5 through the G-γ like (GGL) domain and the disheveled-EGL10-Pleckstrin homology (DEP) domain [6]. The DEP and DEP helical extension domain interact with R7 binding protein (R7BP) or RGS9 anchoring protein (R9AP; in retina) that serves as a plasma membrane anchoring mechanism [3-4].
