Dinucleases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.

GTPBP7, NSUN4, and MTERF4 facilitate maturation of the peptidyl transferase center of the mitochondrial ribosome.

Electrophysiological and structural characterizations reveal that a previously proposed ion channel responsible for sensing mechanical pain is insensitive to poking or stretching stimuli for conducting ions and may serve as a coenzyme A-binding protein instead.

The 3D structures of a membrane protein called TMEM120A suggest that it may act as an enzyme in fat metabolism rather than as an ion channel that senses mechanical pain.

The cryo-electron microscopy structures of inactive and active states of calcium-sensing receptor (CaSR) reveal the activation mechanisms of CaSR.

Direct single molecule visualization of striated muscle relaxation using thin filament tightropes reveals the concerted release of myosins, with implications for models of muscle function.

Analysis of conformational heterogeneity in cryo-EM data by a recently developed deep learning method reveals the structure and dynamics of the oncogenic chromatin remodeler ALC1 bound to a poly-ADP-ribosylated nucleosome.

The diguanylate cyclase activity of SiaD is activated by its binding partner SiaC thourgh a dynamic mechanism of promoting the formation of active SiaD dimers.

Spike protein of SARS-CoV-2 with mutation N501Y shows a faster association rate, slower dissociation rate, and higher binding probability and unbinding force to its human receptor protein ACE2, leading to higher transmission.

The inhibitory protein DEPTOR make two widely separated interactions with mTOR that are both necessary for its unique partial mTOR inhibition, and DEPTOR is a more potent inhibitor of mutation- or RHEB-activated mTORC1 than basal mTORC1.
