Lysosomes catabolize and recycle lipids and other biological molecules to maintain cellular homeostasis in diverse nutrient environments. Lysosomal lipid catabolism relies on the stimulatory activity of bis(monoacylglycero)phosphate (BMP), ...
Molecular Machines that Facilitate Bacterial Outer Membrane Protein Biogenesis [0.03%]

Almost all outer membrane proteins (OMPs) in Gram-negative bacteria contain a β-barrel domain that spans the outer membrane (OM). To reach the OM, OMPs must be translocated across the inner membrane by the Sec machinery, transported across...

CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR-associated nuclease) defense systems have been naturally coopted for guide RNA-directed transposition on multiple occasions. In all cases, cooption occurred with d...

Methylation of RNA nucleotides represents an important layer of gene expression regulation, and perturbation of the RNA methylome is associated with pathophysiology. In cells, RNA methylations are installed by RNA methyltransferases (RNMTs)...

DNA replication and transcription occur in all living cells across all domains of life. Both essential processes occur simultaneously on the same template, leading to conflicts between the macromolecular machines that perform these function...

Mammalian mitochondrial DNA (mtDNA) is replicated and transcribed by phage-like DNA and RNA polymerases, and our understanding of these processes has progressed substantially over the last several decades. Molecular mechanisms have been elu...

Lysosomes are the degradative endpoints of material delivered by endocytosis and autophagy and are therefore particularly prone to damage. Membrane permeabilization or full rupture of lysosomal or late endosomal compartments is highly delet...

Molecular docking has become an essential part of a structural biologist's and medicinal chemist's toolkits. Given a chemical compound and the three-dimensional structure of a molecular target-for example, a protein-docking methods fit the ...
The Story of RNA Unfolded: The Molecular Function of DEAD- and DExH-Box ATPases and Their Complex Relationship with Membraneless Organelles [0.03%]
解开RNA的故事：DEAD-和DExH-盒ATP酶的分子功能及其与无膜细胞器的复杂关系

Kerstin Dörner
DEAD- and DExH-box ATPases (DDX/DHXs) are abundant and highly conserved cellular enzymes ubiquitously involved in RNA processing. By remodeling RNA-RNA and RNA-protein interactions, they often function as gatekeepers that control the progre...
A Cool Look at Positive-Strand RNA Virus Replication Organelles: New Insights from Cryo-Electron Microscopy [0.03%]
