Title: Get4/5-mediated remodeling of Get3's substrate-binding chamber: Insights into tail-anchored protein targeting by the GET pathway.
Authors: Diego Granados-Villanueva / Andrew Rossow / Kelly H Kim /
Abstract: The Guided Entry of Tail-Anchored Proteins (GET) pathway ensures accurate targeting of Tail-Anchored proteins (TAs)-a diverse class of membrane proteins-to the endoplasmic reticulum (ER) membrane. In ...The Guided Entry of Tail-Anchored Proteins (GET) pathway ensures accurate targeting of Tail-Anchored proteins (TAs)-a diverse class of membrane proteins-to the endoplasmic reticulum (ER) membrane. In yeast, newly synthesized TAs are captured by Sgt2 and transferred to Get3 for delivery to the ER, where they undergo subsequent membrane insertion. Efficient and protected handoff of hydrophobic TAs from Sgt2 to Get3 is facilitated by the Get4/5 complex, which is thought to act as a scaffold to position TA-bound Sgt2 and Get3 in proximity while trapping Get3 in an ATP-bound conformation necessary for TA binding. To define the molecular basis for this process, we determined the cryo-EM structure of the Saccharomyces cerevisiae Get3-Get4/5 complex at 3.2 Å resolution. Our structure shows that Get4/5 remodels Get3's TA-binding chamber by unfolding helices that form the lateral walls of the chamber. We termed this region the "lateral gate," as its helix-to-coil transition makes the TA-binding chamber more solvent accessible. Molecular dynamics simulations highlighted the flexibility of the lateral gate, indicating it is structurally dynamic and prone to conformational changes. Mutagenesis studies showed that the lateral gate residues influence both the binding affinity of Get3 for Get4/5 and its ATPase activity. Additionally, our cryo-EM map shows that the Sgt2-binding domain of Get5 is positioned near the lateral gate opening of Get3's TA-binding chamber. Based on these findings, we propose a model in which Get4/5 opens Get3's TA-binding chamber to form a lateral opening, enabling protected, lateral transfer of TAs from Sgt2 to Get3.

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.
