It has been a pleasure to watch @jmella.bsky.social lead this project - a technical tour de force that brought saturation mutagenesis to cardiomyocytes for the first time, revealed CM-specific effects of LMNA mutations + new features of lamin structure and quality control.

Happy to share the latest work from the lab, led by @mudgal17.bsky.social‬, in collaboration with the Weis lab @ethzurich.bsky.social. How do nuclear membranes fuse during NPC assembly? We answer this question in our latest work, where we identify a new mechanism for membrane fusion… (1/13)

Now out @natbiotech.nature.com ! Do lncRNAs commonly bind 1000s of genomic sites? Maybe they do, but the dozens of studies that report genomic binding maps of lncRNAs are deeply flawed, with probes binding suprious DNA sites rather than RNA-bound ones.
