The humanin gene is found within the 16S rRNA gene (MT-RNR2) in the mitochondrial genome

Humanin is a micropeptide encoded in the mitochondrial genome by the 16S ribosomal RNA gene, MT-RNR2. Its structure contains a three-turn α-helix, and no symmetry.

In in vitro and animal models, it appears to have cytoprotective effects.[3][4][5][6]
