MOTS-c (mitochondrial open reading frame of the 12S rRNA-c ) is a peptide encoded in mitochondrial DNA . It is believed to be involved in skeletal muscle and glucose metabolism. It is upregulated in response to exercise, and is considered an exercise mimetic .[ 1] [ 2]
MOTS-c binds to casein kinase 2 .[ 3]
Society and culture
Researchers discovered MOTS-c in 2015.[ 4]
MOTS-c is not approved to treat any medical condition and is banned by the World Anti-Doping Agency , explicitly beginning in 2024.[ 5]
