A labeled dataset for AI-based cryo-EM map enhancement

open access: yesComputational and Structural Biotechnology Journal
Cryogenic electron microscopy (cryo-EM) has transformed structural biology by enabling near atomic resolution imaging of macromolecular complexes. However, cryo-EM density maps suffer from intrinsic noise arising from structural sources, shot noise, and ...

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Cryo-EM advances in RNA structure determination

open access: yesSignal Transduction and Targeted Therapy, 2022
Cryo-electron microscopy (cryo-EM) has emerged as an unprecedented tool to resolve protein structures at atomic resolution. Structural insights of biological samples not accessible by conventional X-ray crystallography and NMR can be explored with cryo ...

Fast multiscale reconstruction for Cryo-EM

open access: yesJournal of Structural Biology, 2018
We present a multiscale reconstruction framework for single-particle analysis (SPA). The representation of three-dimensional (3D) objects with scaled basis functions permits the reconstruction of volumes at any desired scale in the real-space. This multiscale approach generates interesting opportunities in SPA for the stabilization of the initial ...

Atomic cryo-EM structures of viruses [PDF]

open access: yesCurrent Opinion in Structural Biology, 2017
During the development of single particle cryo-EM in past five decades, icosahedral viruses have led the resolution progress owing to their large mass and high symmetry. Many technical advances in cryo-EM were first established with viruses. Since reaching ∼4Å resolution in 2008, it has become a relatively routine task to solve the atomic structure of ...

Cryo-EM structure of GALR2 complex with galanin.

open access: yes, 2022
(A) The molecular structure of GALR2 complex is shown both as cryo-EM map and ribbon diagram. GALR2, mGαqiN, Gβ1, Gγ2, and scFv16 are colored in blue, red, yellow-orange, marine, and lemon, respectively.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

LipIDens: simulation assisted interpretation of lipid densities in cryo-EM structures of membrane proteins

open access: yesNature Communications, 2023
Cryo-electron microscopy (cryo-EM) enables the determination of membrane protein structures in native-like environments. Characterising how membrane proteins interact with the surrounding membrane lipid environment is assisted by resolution of lipid-like
