The development of high-throughput RNA structure profiling methods in the past decade has greatly facilitated our ability to map and characterize different aspects of RNA structures transcriptome-wide in cell populations, single cells and single molecules. The resulting high-resolution data have provided...
New structures of MHC molecules have significantly improved our understanding of molecular recognition in cellular immunology. Highlights include the first structure of a class II MHC molecule, complexed with a viral peptide and with a bacterial superantigen. A structure of an MHC-like Fc receptor is...
The arrangement of atoms, ions, or molecules in a crystal. Crystals are solids having, in all three dimensions of space, a regular repeating internal unit of structure. Crystals have been studied using x-rays, which excite signals from the atoms. The signals are of different strengths and de...
In biology, the structures of proteins determine their functions and how they interact with other molecules. (在生物学中,蛋白质的结构决定了它们的功能以及它们如何与其他分子相互作用。) The social structures of different cultures can vary greatly, influencing how people interact and communicate. (不同...
Existing RNA-targeted small molecules use a range of mechanisms including directing splicing — by acting as molecular glues with cellular proteins (such as branaplam and the FDA-approved risdiplam), inhibition of translation of undruggable proteins and deactivation of functional structures in noncoding...

SIRT3 is directly involved in the regulation of the TCA cycle and fatty acid synthesis through increasing pools of acetyl-CoA molecules by deacetylation and subsequent activation of acetyl-CoA synthetase (ACS) Lys-642 [122] and plays a significant role in the powerhouse of the cell and its fun...

Location of the tRNA Molecules As shown in Figure 3, the difference maps between the reconstructions of the ribosomes engaged in protein synthesis and the nontranslating ribosome are all dominated by a central region of high intensity precisely in the position where tRNA molecules are expected to ...
