BASP1 Couples Ca2+ Signaling and Actin Polymerization to Mitochondrial Fission Essential for Neurite Outgrowth

Ekaterina A. Grebenik, Sofia Zaichick, Angel Gomez, Gabriela Caraveo

This study identifies BASP1 as a Ca2+-CaN-regulated protein that links actin dynamics to mitochondrial fission, essential for neurite outgrowth and neuroprotection.

Calcineurin-mediated regulation of GAP-43 is essential for neurite and synapse formation and protects against α-synuclein-induced degeneration

Sofia Zaichick, Ekaterina A. Grebenik, Gabriela Caraveo

The paper shows that calcineurin-mediated phosphorylation of GAP-43 is critical for neurite and synapse formation and protects against α-synuclein-induced degeneration.
