Humanin (MT-RNR2)

Plays a role as a neuroprotective element. Protects against death induced by numerous familial Alzheimer disease genes and amyloid-beta proteins in Alzheimer disease.

Suppresses apoptosis by binding to BAX and preventing the translocation of BAX from the cytosol into mitochondria. Binds to IGFBP3 and especially blocks IGFBP3-induced cell death Induces chemotaxis of mononuclear phagocytes through FPR2.
