Dynamic Cap‐Mediated Substrate Access and Potent Inhibitor Design of Monkeypox Virus I7L Protease
The first crystal structure of MPXV I7L protease, revealing its unique dimeric form is resolved. The structures and MD simulations uncovered a dynamic cap region that regulates substrate access to the active site. The structural basis of substrate recognition and the catalytic mechanism are elucidated, which led to the development of a FRET‐based assay

A Novel OsMPK6‐OsMADS47‐PPKL1/3 Module Controls Grain Shape and Yield in Rice
OsMADS47 is identified as a key regulator governing rice grain morphology. Phosphorylation‐dependent regulation of its activity directs the development of slender versus round grains, modulating both yield and appearance. This mechanism bridges cellular signaling with transcriptional regulation, establishing a molecular framework for grain optimization.
