🎉Thrilled to share our most recent work on how the lipid environment finely regulates the Golgi V-ATPase. A big THANK YOU to everyone in the Ikonen lab @IkonenLab @MiesvdStoel @rollingmeow, and our collaborators. 🔬Read more: biorxiv.org/content/10.1101/…

Control of Golgi- V-ATPase through Sac1-dependent co-regulation of PI(4)P and cholesterol

Sac1 is a conserved phosphoinositide phosphatase, whose loss-of-function compromises cell and organism viability. Here, we employed acute auxin-inducible Sac1 degradation to identify its immediate...

Happy to share our new work on human cell engineering with an improved version of auxin-inducible degron system. A great collaboration between IkonenLab @IkonenLab and Taneli Lab @RaivioTaneli in University of Helisinki. biorxiv.org/content/10.1101/…

One-step generation of auxin-inducible degron cells with high-efficiency homozygous tagging

Auxin-inducible degron (AID) technology is powerful for chemogenetic control of proteolysis. However, generation of human cell lines to deplete endogenous proteins with AID remains challenging....

Are you curious about the function of DFCP1 in autophagy? Have a look at our latest preprint - we find that it is an ATPase involved in selective autophagy! @kschink @harald_stenmark @TerjeJohansen17 @VeijoS @CanCell_UiO @IkonenLab @tankiawee biorxiv.org/content/10.1101/…

ATPase activity of DFCP1 controls selective autophagy

Cellular homeostasis is governed by removal of damaged organelles and protein aggregates by selective autophagy mediated by cargo adaptors such as p62/SQSTM1. Autophagosomes can assemble in special...
