-   The RGS1 protein, part of the Regulators of G-protein signalling (RGS) family, contains a conserved core domain for GTPase activating protein (GAP) activity and N- and C-terminal motifs that confer distinct functions, with both the N-terminal and the RGS box of RGS1 inhibiting GPCR signalling, suggesting that the overall structure of the N-terminal region of RGS1, rather than specific motifs or residues, is required for its function [[PMID: 12618216]](https://www.ncbi.nlm.nih.gov/pubmed/12618216).
