Description | MOTS-c (Mitochondrial ORF of the Twelve S proteins-c) is a 16-amino-acid peptide. MOTS-c emerges as a key player in mitochondrial regulation, impacting various metabolic functions and stress responses. Ongoing research may uncover further therapeutic applications and clinical implications. |
Targeting Muscle and Metabolism | Acts on muscle tissue. Regulates metabolism through the folate-purine-AMPK pathway. |
Mediator of Mitochondrial Regulation | Regulates insulin and metabolic homeostasis. Key role in metabolic functions. |
Stress-Induced Expression | Significantly expressed in response to stress or exercise. Translocates to the nucleus during metabolic stress. |
Nuclear Gene Expression | Directs the expression of nuclear genes during metabolic stress. Promotes cell balance and stress adaptation. |
These include humanin, and the recently discovered mitochondrial open reading frame of the 12S rRNA-c (MOTS-c). Although more research is needed, we suggest that the m.1382A>C polymorphism located in the MOTS-c encoding mtDNA, which is specific for the Northeast Asian population, may be among the putative biological mechanisms explaining the high longevity of Japanese people.
Here, we report that mitochondrial-encoded MOTS-c can significantly enhance physical performance in young (2 mo.), middle-age (12 mo.), and old (22 mo.) mice. MOTS-c can regulate (i) nuclear genes, including those related to metabolism and proteostasis, (ii) skeletal muscle metabolism, and (iii) myoblast adaptation to metabolic stress.
