New preprint about SPARK on bioRxiv!

16 May 2026

We are happy to announce that our discovery of the SPARK complex is now out on bioRxiv! This has been a big collaborative effort led by the Pauli lab (IMP, Vienna) and Ikawa lab (University of Osaka, Japan), uncovering a conserved fertilizatioan complex in mouse and zebrafish that couples sperm-egg binding to membrane fusion. Congrats to the two joint first authors Victoria and Johannes for leading this work and everyone else involved!
