📢 (1/2) Excited to share the first preprint from my PostDoc! We developed UbSeRP to map co-translational ubiquitination in a translatome-wide, revealing thousands of quality control sites, and how they reshape with aging. www.biorxiv.org/content/10.6... #proteostasis #ribosomes #preprint

Ubiquitin selective ribosome profiling reveals systematic principles of co-translational quality control
Protein biogenesis is a stress- and error-sensitive process that can lead to nascent protein misfolding and aggregation, challenging cellular proteostasis. Co-translational ubiquitination (CTU) is a c...

Excited to share our paper about copick, a dataset API and toolkit for collaborative annotation and analysis of #cryoET data! Whether you're picking particles or curating segmentations, copick reduces friction and brings #OME-Zarr to cryoET without breaking pipelines. 🧵👇 doi.org/10.1002/pro.70578

Out now in Nature Communications! We show that Dictyostelium vaults associate with ER and NE membranes in situ and encapsulate ribosomes with defined orientations, shining new light on their cellular function! #TeamTomo #TeamMassSpec #ProtistsOnSky www.nature.com/articles/s41...

Ribosomal RNA expansion segments mediate the oligomerization of inactive animal ribosomes
Cells down-regulate protein synthesis when stressed to conserve energy and shift resources toward repair. We found that in some mammalian cells, including neurons, stress also resulted in the formatio...
