Title: Structural insights into integrin αβ opening by fibronectin ligand.

Abstract: Integrin αβ is a major fibronectin receptor critical for cell migration. Upon complex formation, fibronectin and αβ undergo conformational changes. While this is key for cell-tissue connections, ...Integrin αβ is a major fibronectin receptor critical for cell migration. Upon complex formation, fibronectin and αβ undergo conformational changes. While this is key for cell-tissue connections, its mechanism is unknown. Here, we report cryo-electron microscopy structures of native human αβ with fibronectin to 3.1-angstrom resolution, and in its resting state to 4.6-angstrom resolution. The αβ-fibronectin complex revealed simultaneous interactions at the arginine-glycine-aspartate loop, the synergy site, and a newly identified binding site proximal to adjacent to metal ion-dependent adhesion site, inducing the translocation of helix α1 to secure integrin opening. Resting αβ adopts an incompletely bent conformation, challenging the model of integrin sharp bending inhibiting ligand binding. Our biochemical and structural analyses showed that affinity of αβ for fibronectin is increased with manganese ions (Mn) while adopting the half-bent conformation, indicating that ligand-binding affinity does not depend on conformation, and αβ opening is induced by ligand-binding.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
