A graphical block depiction (A) of the multiple functional regions of human GRK5 indicates the diverse range of activities mediated by this protein (α-N, terminal domain; PIP2, phosphatidylinositol bisphosphate binding domain; RH, Regulator of G protein signaling homology domain; NES, Nuclear Export Sequence; NLS, Nuclear Localization Sequence). In the primary sequence two autophosphorylation sites are indicated within the catalytic domain. A crystal-assisted model of human GRK5 (B) was constructed and annotated using 3DBionotes-WS (http://3dbionotes.cnb.csic.es/ws). This model indicates the three-dimensional proximities of the α-N domain (green), PIP2 binding domains (blue), NES (pink), catalytic domain (orange), and the NLS domain (red).
