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).

Excited to share our latest manuscript by @saikat2025.bsky.social and an international team, reporting variants in the EARP- and GARP-interacting protein EIPR1 associated with a neurodevelopmental disorder. Will send you the PDF if you can’t access the article: academic.oup.com/brain/articl...
EIPR1 variants cause a neurodevelopmental disorder with endolysosomal and dense core vesicle defects
Abstract. EIPR1 (EARP-interacting protein 1, formerly known as TSSC1) is a WD40-domain protein that interacts with the EARP (endosome-associated recycling

Much needed good news!! Our paper is just out in @jcb.org. We found a crazy antagonistic motor function that explains the elongation/retraction phenotype we see during LRRK2-dependent lysosomal tubulation. I am especially proud of Tsion, Nuria, Mia and Irene's contribution. Check it out!

One for the Apicomplexa peeps:
ever wonder how does the IMC grow so fast during progeny formation? Where do all the lipids come from? In our latest work on malaria RBC stages we implicate this monster protein (~6000 residues!) and ER contact sites.
