Molecular mechanism of naturally-encoded signaling-bias at the complement anaphylatoxin receptors

This paper identifies naturally-encoded signaling bias at C5aR1 and C5aR2 receptors through structural and functional analyses, revealing molecular mechanisms underlying biased signaling in GPCRs.

Molecular basis of promiscuous chemokine-engagement by the Duffy antigen receptor

This study determines the cryo-EM structures of DARC bound to chemokines CCL7 and CXCL8, revealing unique binding mechanisms and the role of tyrosine sulfation and allelic variation in chemokine engagement.

Atypical activation and molecular glue-like dimerization mechanism of an intrinsically-biased chemokine receptor

This study reveals an atypical activation mechanism of CXCR7, identifies its role as an opioid receptor, and highlights potential for novel pain therapeutics.

Molecular fingerprints of a convergent mechanism orchestrating diverse ligand recognition and species-specific pharmacology at the complement anaphylatoxin receptors

This study identifies a convergent molecular mechanism and species-specific pharmacology in complement anaphylatoxin receptors through structural and functional analyses of ligand-receptor interactions.
