PolyA/polyQ-mediated conformational rewiring regulates DNA engagement and drives aggregation in the neuronal transcription factor Ascl1

Shrutarshi Mitra, Sarah F. Ruidiaz, Asdis Laufeyjardottir, Vasileios Voutsinos, Kateryna Nitsenko, Andrea Guala, Kenneth S. Zaret, Rasmus Hartmann‐Petersen, Pétur O. Heidarsson

This study shows that the polyA/polyQ tract in Ascl1 regulates DNA engagement and aggregation through conformational changes, affecting solubility and cellular abundance.

A Structural Domain in the genomic RNA of SARS-CoV-2 Folds into a Compact Granular Structure without the N protein: A Single-Molecule Fluorescence Spectroscopic Investigation

Takahiro Kimura, Takuya Katayama, Shion Ishikawa, Shrutarshi Mitra, Yuuhei Yamano, Kazumitsu Onizuka, Fumi Nagatsugi, Shilpi Laha, Athi N. Naganathan, Yuji Itoh, Satoshi Takahashi

This study shows a specific SARS-CoV-2 genomic RNA region forms compact granular structures autonomously without the N protein, and the N protein melts these structures, suggesting it acts as an RNA chaperone.
