Excited to see this study, in collaboration with the De Camilli group @pdc-lab.bsky.social, published in its final format! We resolved the structure of VPS13C and found that it adopts a lipid-transfer-incompetent conformation. We also show that CaM binds VPS13s and may help regulate their function.

Cryo-EM structure of soluble VPS13C suggests its regulation by a conformational switch and by calmodulin
VPS13C, whose dysfunction causes Parkinson’s disease, adopts a lipid-transfer-inactive conformation in the cytoplasm and relies on calmodulin for proper folding and localization to membrane surfaces.

Do you like following rules… but also breaking them? So does your dopaminergic synapse! 😎🧠 Our new Trends in Neurosciences review dives into the non-classical side of dopamine signaling, notably the tools reshaping how we see it (CLEM, cryo-CLEM, serial EM + more).
