Data supplement for: Disrupting cortico-cerebellar communication impairs dexterity

Britton Sauerbrei, Jian-Zhong Guo, Jeremy Cohen, Matteo Mischiati, Austin Graves, Ferruccio Pisanello, Kristin Branson & Adam Hantman
This dataset, along with the corresponding code, is a supplement to “Disrupting cortico-cerebellar communication impairs dexterity” (Guo*, Sauerbrei* et al., eLife 2021). It consists of single-unit electrophysiology data from the pontine nuclei, Purkinje cells, cerebellar nuclei, and motor cortex of awake mice, along with measurements of the hand position of mice performing reaching movements. These data address the question of how the dynamics of motor cortex and cerebellum interact to control skilled reaching. First, we...

A dominant-negative SOX18 mutant disrupts multiple regulatory layers essential to transcription factor activity

Few genetically dominant mutations involved in human disease have been fully explained at the molecular level. In cases where the mutant gene encodes a transcription factor, the dominant-negative mode of action of the mutant protein is particularly poorly understood. Here, we studied the genome-wide mechanism underlying a dominant-negative form of the SOX18 transcription factor (SOX18RaOp) responsible for both the classical mouse mutant Ragged Opossum and the human genetic disorder Hypotrichosis-Lymphedema-Telangiectasia-Renal Syndrome. Combining three single-molecule imaging...

Pinpointing the neural signatures of single-exposure visual recognition memory

Vahid Mehrpour, Travis Meyer, Eero P. Simoncelli & Nicole C. Rust
Memories of the images that we have seen are thought to be reflected in the reduction of neural responses in high-level visual areas such as inferotemporal (IT) cortex, a phenomenon known as repetition suppression (RS). We challenged this hypothesis with a task that required rhesus monkeys to report whether images were novel or repeated while ignoring variations in contrast, a stimulus attribute that is also known to modulate the overall IT response. The monkeys’ behavior...

A phase-separated nuclear GBPL circuit controls immunity in plants

Shuai Huang, Shiwei Zhu, Pradeep Kumar & John MacMicking
Liquid-liquid phase separation (LLPS) has emerged as a central paradigm for understanding how membrane-less organelles compartmentalize diverse cellular activities in eukaryotes. Here, we identified a new superfamily of plant Guanylate-Binding Protein-Like GTPases (GBPLs) that assemble LLPS-driven condensates within the nucleus to protect against infection and autoimmunity. In Arabidopsis thaliana, two family members - GBPL1 and GBPL3 - undergo phase transition behavior to control transcriptional responses as part of an allosteric switch triggered by exposure to...
