Publication: Xist spatially amplifies SHARP/SPEN recruitment to balance chromosome-wide silencing and specificity to the X chromosome
Why are lncRNAs lowly expressed? How can they regulate their more abundant targets? Our latest paper “Xist spatially amplifies SHARP/SPEN recruitment to balance chromosome-wide silencing and specificity to the X chromosome” published in Nature Structural & Molecular Biology explores how these features are balanced to ensure target specificity and robust gene regulation via a spatial amplification mechanism.

Publication: SPRITE, a genome-wide method for mapping higher-order 3D interactions in the nucleus using combinatorial split-and-pool barcoding
Want to generate higher-order 3D maps of DNA organization? Our protocol for DNA-SPRITE, ” SPRITE: a genome-wide method for mapping higher-order 3D interactions in the nucleus using combinatorial split-and-pool barcoding” is now live on Nature Protocols! Read the protocol paper here
Guttman Lab Retreat 2021
Guttman lab celebrates a happy return to our favorite tradition, the annual lab retreat. This year’s event was held December 10-12 in the mountain town of Lake Arrowhead, California. Lab members presented their work, discussed next year’s goals and opportunities, and drew out a roadmap for another year of research. But that’s not all, we took plenty of time to relax, hike, and make s’mores in this idyllic mountain setting.

Revealing chromosome contours, one dot at a time
Nature interviews Guttman Lab in this week’s Technology Feature discussing the latest technological advances for studying 3D genome organization. In concert with the in situ microscopy renderings created at Caltech’s Cai Lab, Guttman Lab’s SPRITE method has opened the door to discovery driven proximity interactions – even long distance interactions. Even lab mascot SHARP-y made the feature! Read the full article at Nature.com
The Vast Little Library Inside of Your Cells
Featured this week in Caltech News: Using the latest innovation developed at Guttman Lab, RNA-DNA SPRITE, our team discovered that non-coding RNA create “compartments” within the nucleus and shepherd key molecules to precise regions in the genome. Read this review now at Caltech News
