Honored to see our work featured in a JCB Spotlight by Pacheco and @drericabiophd.bsky.social (@UCSF). The piece discusses our study revealing distinct force-generating mechanisms in epithelial and mesenchymal collective migration 🔬🐸 Thank you for your careful review of our work! hubs.la/Q042GFYY0

Made a bluesky account especially for this - our new spotlight on a really interesting new paper is now available to read! Findings that go against what "should" be based on current knowledge are always some of my favourite discussions to have, one of the great joys of being in Biology. 🧬

New paper in @jcb.org! We found a new regulator of p62 phase separation, autophagy, and antioxidant signaling. It is an E3 ligase adaptor called SHKBP1, but the effect is via direct p62 binding, not ubiquitination. Congrats to Lin Luan & team! @weillinstitute.bsky.social
