Citation | Journal: Nat Commun / Year: 2022 Title: Structural basis of FPR2 in recognition of Aβ and neuroprotection by humanin. Authors: Ya Zhu / Xiaowen Lin / Xin Zong / Shuo Han / Mu Wang / Yuxuan Su / Limin Ma / Xiaojing Chu / Cuiying Yi / Qiang Zhao / Beili Wu / Abstract: Formyl peptide receptor 2 (FPR2) has been shown to mediate the cytotoxic effects of the β amyloid peptide Aβ and serves as a receptor for humanin, a peptide that protects neuronal cells from damage ...Formyl peptide receptor 2 (FPR2) has been shown to mediate the cytotoxic effects of the β amyloid peptide Aβ and serves as a receptor for humanin, a peptide that protects neuronal cells from damage by Aβ, implying its involvement in the pathogenesis of Alzheimer's disease (AD). However, the interaction pattern between FPR2 and Aβ or humanin remains unknown. Here we report the structures of FPR2 bound to G and Aβ or N-formyl humanin (fHN). Combined with functional data, the structures reveal two critical regions that govern recognition and activity of Aβ and fHN, including a polar binding cavity within the receptor helical bundle and a hydrophobic binding groove in the extracellular region. In addition, the structures of FPR2 and FPR1 in complex with different formyl peptides were determined, providing insights into ligand recognition and selectivity of the FPR family. These findings uncover key factors that define the functionality of FPR2 in AD and other inflammatory diseases and would enable drug development. | ||||||||||||
