Most metabolic peptides are transcribed from nuclear DNA, but MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is encoded directly within the mitochondrial genome. In our analytical discussions, MOTS-c stands out as a fascinating signaling molecule that acts as an intracellular energy gauge and systemic metabolic regulator.
Activating the AMPK Energy Sensing Pathway
When cellular energy levels drop, MOTS-c translocates to the nucleus and directly regulates adaptive nuclear gene expression. In skeletal muscle assays, it activates AMP-activated protein kinase (AMPK), enhancing glucose uptake and fatty acid oxidation independently of insulin signaling.
- Mitochondrial Signaling: Directly links mitochondrial function to systemic glucose disposal and metabolic flexibility.
- Exercise Mimetics: Reproduces the biochemical signaling cascades typically induced by intense physical endurance training in cellular models.
Because MOTS-c is highly sensitive to environmental degradation, verifying synthesis purity via HPLC is non-negotiable. We spend over €300 per batch on independent European laboratory analysis so you never have to question your experimental reagents.
