Besides tau phosphorylation, calpain activation might play a role in tau-mediated neurodegeneration by inducing tau cleavage. In vitro studies have shown that both fetal and adult tau isoforms are rapidly proteolyzed by calpains |

Calpains also modulate the activity of CDK5. Physiologically, CDK 5 is activated by p35 and its cleaved product p25. The latter has a longer half life than p35 and therefore it is a more potent activator of CDK5. The cleavage of p35 to p25 is mediated by calpain |

In addition to Ca2+, calpastatin has a key role in the regulation of calpain. Calpastatin, a heat-stable protein ranging from ~70 to ~140 kDa of apparent molecular weight depending on the cell type, is considered a specific endogenous inhibitor of calpains|The calpastatin molecule contains four inhibitory units [75–77]. Each of these units binds to one calpain molecule [75–77]. Therefore, the ratio calpain/calpastatin plays a key role in the regulation of calpain activity [78–80]. The inhibitory effect of calpastatin requires Ca2+-dependent high-affinity binding to three sites of calpain |

The data obtained from those studies suggest that the mechanisms leading to the formation of the hallmark lesions of AD might be linked. One of such mechanisms seems to be the dysregulation of calcium homeostasis that results in the abnormal activation of calpains. Calpains are a family of Ca2+-dependent cysteine proteases that play a key role in multiple cell functions including cell development, differentiation and proliferation, axonal guidance, growth cone motility, and cell death, among others. |
