One last piece of news to cap off the year.... the Lee lab is now funded by an✨NSF CAREER✨ We'll explore how transgenerational inheritance affects the earliest decisions in C. elegans embryos AND build new CUREs for our first-gen students. 🪱🧬 Funding makes us feel 👇

In a time as this— I am deeply thankful to be blessed with this honor. As a scientist and educator, the NSF CAREER award allows me to integrate the very core of who I am as a scientist and educator. Forever grateful to past and present members of the @mcreynolds_lab for helping me accomplish this dream.

we extended our simulations to the full length heterodimer complex between FXR and RXR (retinoid X receptor alpha). We revealed a variety of underappreciated roles for the FXR hinge in the context of the dimer, including in DNA binding, interdomain allostery and dimer flexibility
