Description
What is MOTS-c?
MOTS-c is a 16-amino-acid peptide discovered in 2015 and encoded within an open reading frame of the mitochondrial 12S ribosomal RNA gene. As a mitochondrial-derived peptide it represents retrograde signaling from the mitochondrion to the cell. In research models it circulates systemically and is investigated as a metabolic regulator linking mitochondrial status to nuclear gene expression and energy balance, particularly under metabolic and oxidative stress.
How MOTS-c works (research context)
In laboratory studies MOTS-c functions primarily as an activator of AMP-activated protein kinase (AMPK), the cell's central energy sensor. Mechanistic work indicates it modulates the folate-methionine one-carbon cycle and purine biosynthesis, driving accumulation of the AMPK-activating intermediate AICAR. Under metabolic stress it translocates from the mitochondria to the nucleus, where it is studied for influence on antioxidant and metabolic gene programs.

COA emailed ahead, cold chain intact. No cloudiness on reconstitution. Reordering for the next study.
Dr. Yara Okafor (verified owner) –
MOTS-c reconstituted clean and our AMPK phosphorylation Western blots were textbook. 98.9% on the COA, confirmed in-house.
Dr. Priscila Gomes (verified owner) –
Translocation studies under metabolic stress worked beautifully with this lot. Reliable, well-handled peptide.
N. Brennan (verified owner) –
Good purity, clear COA. Vial fill was slightly under but within reason. Shipping was prompt and cold.
