Citation | Journal: Mol Cell / Year: 2023 Title: Structural snapshots uncover a key phosphorylation motif in GPCRs driving β-arrestin activation. Authors: Jagannath Maharana / Parishmita Sarma / Manish K Yadav / Sayantan Saha / Vinay Singh / Shirsha Saha / Mohamed Chami / Ramanuj Banerjee / Arun K Shukla / Abstract: Agonist-induced GPCR phosphorylation is a key determinant for the binding and activation of β-arrestins (βarrs). However, it is not entirely clear how different GPCRs harboring divergent ...Agonist-induced GPCR phosphorylation is a key determinant for the binding and activation of β-arrestins (βarrs). However, it is not entirely clear how different GPCRs harboring divergent phosphorylation patterns impart converging active conformation on βarrs leading to broadly conserved functional responses such as desensitization, endocytosis, and signaling. Here, we present multiple cryo-EM structures of activated βarrs in complex with distinct phosphorylation patterns derived from the carboxyl terminus of different GPCRs. These structures help identify a P-X-P-P type phosphorylation motif in GPCRs that interacts with a spatially organized K-K-R-R-K-K sequence in the N-domain of βarrs. Sequence analysis of the human GPCRome reveals the presence of this phosphorylation pattern in a large number of receptors, and its contribution in βarr activation is demonstrated by targeted mutagenesis experiments combined with an intrabody-based conformational sensor. Taken together, our findings provide important structural insights into the ability of distinct GPCRs to activate βarrs through a significantly conserved mechanism. #1: Journal: Mol.Cell / Year: 2023 Title: Structure of beta-arrestin in complex with a phosphopeptide Authors: Maharana, J. / Sarma, P. / Yadav, M.K. / Banerjee, R. / Shukla, A.K. | ||||||
