About MOTS-c

Residues: 16
Molecular weight: 2174.6 g/mol
CAS number: 1627580-64-6

MOTS-c is a 16-residue mitochondrial-derived peptide encoded by a short open reading frame within the mitochondrial 12S rRNA (MT-RNR1) region. It is studied as a regulator of cellular metabolism, reported to act on the folate-methionine pathway and to activate AMP-activated protein kinase (AMPK) signalling. It is a linear peptide of standard L-amino acids.
