Localization of phosphorylated alphaB-crystallin to heart mitochondria during ischemia-reperfusion.

The cytosolic small heat shock protein alphaB-crystallin (alphaBC) is a molecular chaperone expressed in large quantities in the heart, where it protects from stresses such as ischemia-reperfusion (I/R). Upon I/R, p38 MAP kinase activation leads to …
