The HIV-1 envelope glycoprotein (Env) trimer contains the receptor binding sites and membrane fusion machinery that introduce viral genome into host cell. As only target for broadly neutralizing antibodies (bnAbs), Env is a focus rational vaccine design. We present cryo-electron microscopy reconstruction structural model of cleaved, soluble (termed BG505 SOSIP.664 gp140) in complex with CD4 site (CD4bs) bnAb, PGV04, at 5.8 angstrom resolution. structure reveals spatial arrangement...
This Meeting Review describes the proceedings and conclusions from inaugural meeting of Electron Microscopy Validation Task Force organized by Unified Data Resource for 3DEM (http://www.emdatabank.org) held at Rutgers University in New Brunswick, NJ on September 28 29, 2010. At workshop, a group scientists involved collecting electron microscopy data, using data to determine three-dimensional (3DEM) density maps, building molecular models into maps explored how assess models, other that are...
Single particle cryo-electron microscopy (cryoEM) is often performed under the assumption that particles are not adsorbed to air-water interfaces and in thin, vitreous ice. In this study, we fiducial-less tomography on over 50 different cryoEM grid/sample preparations determine distribution within ice overall geometry of grid holes. Surprisingly, by studying holes 3D from 1000 tomograms, have determined vast majority (approximately 90%) an interface. The implications observation...
Influenza Revealed virus, a single-stranded RNA is responsible for substantial morbidity and mortality worldwide. The influenza ribonucleoprotein (RNP) complex, which carries out viral replication transcription, central to the virus life-cycle host adaptation (see Perspective by Tao Zheng ). Structural characterization of RNP has been challenging, but Moeller et al. (p. 1631 , published online 22 November) Arranz 1634 now report structure assembly this using cryo-electron microscopy...
Cryo-FIB/SEM combined with cryo-ET has emerged from within the field of cryo-EM as method for obtaining highest resolution structural information complex biological samples in-situ in native and non-native environments. However, challenges remain conventional cryo-FIB/SEM workflows, including milling thick specimens vitrification issues, preferred orientation, low-throughput when small and/or low concentration specimens, that distribute poorly across grid squares. Here we present a general...
Mitochondria-ER membrane contact sites (MERCS) represent a fundamental ultrastructural feature underlying unique biochemistry and physiology in eukaryotic cells. The ER protein PDZD8 is required for the formation of MERCS many cell types, however, its tethering partner on outer mitochondrial (OMM) currently unknown. Here we identify OMM FKBP8 as using combination unbiased proximity proteomics, CRISPR-Cas9 endogenous tagging, Cryo-electron tomography, correlative light-electron microscopy....
