1 Stabilization of the GDP-bound conformation of Gialpha by a peptide derived from the G-protein regulatory motif of AGS3. Guanosine Diphosphate G protein signaling modulator 1 Homo sapiens
2 The GPR consensus peptide effectively prevented the binding of AGS3 to Gialpha1,2 in protein interaction assays, inhibited guanosine 5"-O-(3-thiotriphosphate) binding to Gialpha, and stabilized the GDP-bound conformation of Gialpha. Guanosine Diphosphate G protein signaling modulator 1 Homo sapiens
3 The GPR consensus peptide also blocked receptor coupling to Gialphabetagamma indicating that although the AGS3-GPR peptide stabilized the GDP-bound conformation of Gialpha, this conformation of Gialpha(GDP) was not recognized by a G-protein coupled receptor. Guanosine Diphosphate G protein signaling modulator 1 Homo sapiens
4 The GPR consensus peptide also blocked receptor coupling to Gialphabetagamma indicating that although the AGS3-GPR peptide stabilized the GDP-bound conformation of Gialpha, this conformation of Gialpha(GDP) was not recognized by a G-protein coupled receptor. Guanosine Diphosphate G protein signaling modulator 1 Homo sapiens
