Humanin

Also known as: HN, HNG

A mitochondrial-derived peptide with cytoprotective and neuroprotective properties.

Overview

Humanin is a 24 amino acid peptide encoded in the mitochondrial genome. Discovered for its ability to protect neurons, it has broad cytoprotective effects across multiple organ systems.

Mechanism of Action

Binds to BAX to prevent apoptosis. Activates pro-survival signaling through STAT3 and ERK pathways. Enhances insulin sensitivity through IGF-1BP3 interaction.

Pharmacokinetics

Circulating levels decline with age. Modified versions (HNG, HN17) have enhanced potency and stability.
