Parvalbumin expression in oligodendrocyte-like CG4 cells causes a reduction in mitochondrial volume, attenuation in reactive oxygen species production and a decrease in cell processes' length and branching.

Forebrain glial cells - ependymal cells and astrocytes -acquire upon injury- a "reactive" phenotype associated with parvalbumin (PV) upregulation. Since free radicals, e.g.

Four novel interaction partners demonstrate diverse modulatory effects on voltage-gated Ca2.2 Ca channels.

Voltage-gated Ca channels are embedded in a network of protein interactions that are fundamental for channel function and modulation. Different strategies such as high-resolution quantitative MS analyses and yeast-two hybrid screens have been used to uncover these Ca channel nanodomains. We applied the yeast split-ubiquitin system with its specific advantages to search for interaction partners of the Ca2.

Parvalbumin alters mitochondrial dynamics and affects cell morphology.

The Ca-binding protein parvalbumin (PV) and mitochondria play important roles in Ca signaling, buffering and sequestration. Antagonistic regulation of PV and mitochondrial volume is observed in in vitro and in vivo model systems. Changes in mitochondrial morphology, mitochondrial volume and dynamics (fusion, fission, mitophagy) resulting from modulation of PV were investigated in MDCK epithelial cells with stable overexpression/downregulation of PV.
