abstract = {Synaptic signaling depends on ATP generated by
mitochondria. Due to extensive connectivity, the striatum is
especially vulnerable to mitochondrial dysfunction and thus
requires efficient mitochondrial quality control and repair.
We found that global knockout of the neuronal
calcium-binding protein 2 (NECAB2) in the mouse causes loss
of striatal synapses and behavioral phenotypes related to
striatal dysfunction such as reduced motivation and altered
sensory gating. Striatal mitochondria from Necab2 knockout
mice are more abundant and smaller. They are characterized
by increased respiration and superoxide production resulting
in oxidative stress. This accumulation of dysfunctional
mitochondria is caused by a defective assembly of
mitochondria with early endosomes in a pathway that involves
the small GTPase Rab5 and its guanine nucleotide exchange
factor Alsin/ALS2. NECAB2 therefore participates in an
endosomal pathway of mitochondrial stress response and
repair important for striatal function.},
