Very happy to share our new paper in #ScienceSignaling revealing that importin β1 isn’t just important for nuclear transport or neuronal growth.
We now show it is key for presynaptic plasticity in the hippocampus, local translation, and memory!

Subcellular depletion of importin β1 impairs presynaptic local translation and spatial memory
Axonal localization of importin β1 is required for presynaptic functions that support spatial memory tasks.
