Excited to share the cryo-EM structure of the Retriever-SNX17 complex. We also identify additional ligands that bind to the same pocket in Retriever. Great collaboration with the Chen lab, UTSW SBL and the Turer lab. biorxiv.org/content/10.1101/…
Structural basis for Retriever-SNX17 assembly and endosomal sorting

Structural basis for Retriever-SNX17 assembly and endosomal sorting

During endosomal recycling, Sorting Nexin 17 (SNX17) facilitates the transport of numerous membrane cargo proteins by tethering them to the Retriever complex. Despite its importance, the mechanisms...

Lamellipodia – branching out without WAVE

Lamellipodia – branching out without WAVE

The formation of lamellipodia requires the branching of actin filaments; this typically involves Rac GTPases and the WAVE regulatory complex (WRC), which connects Rac activation to actin branching...

Check out our recent manuscript in @NatureComms nature.com/articles/s41467-0… where we show how Rac1 GTPase activates WRC complex to promote actin polymerization by Arp2/3 complex.
Structures reveal a key mechanism of WAVE regulatory complex activation by Rac1 GTPase

Structures reveal a key mechanism of WAVE regulatory complex activation by Rac1 GTPase

Nature Communications - Rho-family GTPase Rac1 activates the WAVE complex (WRC) to promote Arp2/3-mediated actin assembly in various processes. Here, the authors determined cryo-EM structures of...
