The HIV-1 Nuclear Export Complex Reveals the Role of RNA in Crm1 Cargo Recognition

Kavli Affiliate: Keri Martinowich | Authors: Amber M Smith, Yang Li, Arianna Velarde, Yifan Cheng and Alan D. Frankel | Summary: Summary: Crm1 is a highly conserved nuclear exportin that transports >1000 human proteins including ribonucleoprotein (RNP) complexes. The interface between Crm1 and RNP cargos is unknown. The HIV regulatory protein, Rev, was one of […]

Machine-learning convergent melanocytic morphology despite noisy archival slides

Kavli Affiliate: Michael Keiser | Authors: Mikio Tada, Garrett Gaskins, Sina Ghandian, Nicholas Mew, Michael J. Keiser and Elizabeth S. Keiser | Summary: Melanocytic atypia, ranging from benign to malignant, often leads to diagnostic discordance, complicating its prediction by machine learning models. To overcome this, we paired H&E-stained histology images with contiguous or serial sections […]

De novo-designed minibinders expand the synthetic biology sensing repertoire

Kavli Affiliate: Hana El-Samad | Authors: Zara Y. Weinberg, Sarah S. Soliman, Matthew S. Kim, Irene P. Chen, Melanie Ott and Hana El-Samad | Summary: Synthetic and chimeric receptors capable of recognizing and responding to user-defined antigens have enabled “smart” therapeutics based on engineered cells. These cell engineering tools depend on antigen sensors which are […]

HMGB1 restores a dynamic chromatin environment in the presence of linker histone by deforming nucleosomal DNA

Kavli Affiliate: Yifan Cheng | Authors: Hayden S Saunders, Un Seng Chio, Camille M Moore, Vijay Ramani, Yifan Cheng and Geeta Narlikar | Summary: Summary: The essential architectural protein HMGB1 increases accessibility of nucleosomal DNA and counteracts the effects of linker histone H1. However, HMGB1 is less abundant than H1 and binds nucleosomes more weakly […]
