Structural determinants of water permeation through aquaporin-1
Human red cell AQP1 is the first functionally defined member of the aquaporin family of membrane water channels. Here we describe an atomic model of AQP1 at 3.8 Å resolution from electronExpand

STIM1 Clusters and Activates CRAC Channels via Direct Binding of a Cytosolic Domain to Orai1
Store-operated Ca(2+) channels activated by the depletion of Ca(2+) from the endoplasmic reticulum (ER) are a major Ca(2+) entry pathway in nonexcitable cells and are essential for T cell activationExpand

Global Conformational Rearrangements in Integrin Extracellular Domains in Outside-In and Inside-Out Signaling
How ligand binding alters integrin conformation in outside-in signaling, and how inside-out signals alter integrin affinity for ligand, have been mysterious. We address this with electron microscopy,Expand

A Virulence Locus of Pseudomonas aeruginosa Encodes a Protein Secretion Apparatus
Bacterial pathogens frequently use protein secretion to mediate interactions with their hosts. Here we found that a virulence locus (HSI-I) of Pseudomonas aeruginosa encodes a protein secretionExpand

Latent TGF-β structure and activation
Transforming growth factor (TGF)-β is stored in the extracellular matrix as a latent complex with its prodomain. Activation of TGF-β1 requires the binding of αv integrin to an RGD sequence in theExpand

Multiple associated proteins regulate proteasome structure and function.
We have identified proteins that are abundant in affinity-purified proteasomes, but absent from proteasomes as previously defined because elevated salt concentrations dissociate them duringExpand

Molecular model for a complete clathrin lattice from electron cryomicroscopy
Clathrin-coated vesicles are important vehicles of membrane traffic in cells. We report the structure of a clathrin lattice at subnanometre resolution, obtained from electron cryomicroscopy of coatsExpand

Neurodegenerative disease: Amyloid pores from pathogenic mutations
Alzheimer's and Parkinson's diseases are associated with the formation in the brain of amyloid fibrils from β-amyloid and α-synuclein proteins, respectively. It is likely that oligomericExpand

The RIP1/RIP3 Necrosome Forms a Functional Amyloid Signaling Complex Required for Programmed Necrosis
RIP1 and RIP3 kinases are central players in TNF-induced programmed necrosis. Here, we report that the RIP homotypic interaction motifs (RHIMs) of RIP1 and RIP3 mediate the assembly of heterodimericExpand

Negative Staining and Image Classification – Powerful Tools in Modern Electron Microscopy
Vitrification is the state-of-the-art specimen preparation technique for molecular electron microscopy (EM) and therefore negative staining may appear to be an outdated approach. In this paper weExpand
