So similar, yet so different: the paradigm of PARP9 macro domain paralogs

Nikolaos K. Fourkiotis, Christos Sideras‐Bisdekis, Aikaterini C. Tsika…·Georgios A. Spyroulias

This study investigates the functional divergence between two macro domains in PARP9, showing how their distinct thermodynamics and ligand binding dynamics enable their roles as an eraser and a reader.

McIdas localizes at centrioles and controls centriole numbers through PLK4-dependent phosphorylation

Marina Arbi, Margarita Skamnelou, Spyridoula Bournaka…·Zoi Lygerou

This study identifies McIdas as a regulator of centriole numbers through PLK4-dependent phosphorylation, linking its role in cell cycle control to centriole duplication.
