Visao Geral
Visao Geral
MOTS-c (Mitochondrial Open Reading Frame do(a) 12S rRNA-c) is a 16-amino-acid bioactive peptide pertencente a the class of mitochondrial-derived peptides (MDPs).[1]
Unique origin: Diferentemente de virtually all outro(a) bioactive peptides codificado(a) por the nuclear genome, MOTS-c is encoded dentro do(a) mitochondrial genome (mtDNA) — specifically by a short open reading frame (sORF) dentro do(a) mitochondrial 12S rRNA gene (MT-RNR1). Apesar de being mtDNA-encoded, MOTS-c is translated no(a) cytoplasm using the standard genetic code (the mitochondrial code would yield tandem start/stop codons).[1][6]
MOTS-c functions como um(a) mitokine — a mitochondrial hormone que can translocate do(a) mitochondria/cytoplasm para o(a) nucleus under metabolic stress, onde it binds chromatin at Antioxidant Response Elements (ARE) via o(a) Nrf2 transcricao factor, regulating aproximadamente 1,000 genes.[3]
Structurally, MOTS-c is a linear, α-helical, amphipathic and cationic peptide (MW 2174.62 Da) with a hydrophobic core (⁸YIFY¹¹) e um(a) cationic tail (¹³RKLR¹⁶). A naturally occurring polymorphism (K14Q, m.1382A>C) no(a) cationic tail has been associado(a) com exceptional longevity in Japanese populations but reduz CK2 afinidade de ligacao.[7]
MOTS-c differs from Humanin — another MDP codificado(a) por the 16S rRNA region — in que MOTS-c unicamente direciona the folate cycle and nuclear expressao genica.[6]
Mecanismo de Acao
Mecanismo de Acao
Primary Pathway: Folate → AICAR → AMPK ("Master Metabolic Switch")
MOTS-c inibe the folate cycle at 5-methyltetrahydrofolate (5Me-THF), blocking de novo purine biosynthesis. This leads to accumulation of AICAR (5-aminoimidazole-4-carboxamide ribonucleotide), que mimics AMP and ativa diretamente AMPK.[1]
- MOTS-c → inibe folate cycle (5Me-THF)
- Blocked purine synthesis → AICAR accumulation
- AICAR (AMP mimetic) → direto(a) AMPK ativacao
- AMPK → ACC fosforilacao → fatty acid oxidation
- AMPK → GLUT4 translocation → aprimorou glucose uptake
Direct Binding Partners
| Target | Binding Domain | Functional Consequence |
|---|---|---|
| CK2α | Cationic tail (¹³RKLR¹⁶) | Skeletal muscle insulin sensibilizacao; K14Q polymorphism reduz this binding[7] |
| Raptor (mTORC1) | Hydrophobic core (⁸YIFY¹¹) | Allosteric mTORC1 inibicao → shifts T-cell diferenciacao from Th1 to FOXP3+ Tregs[8] |
| Nrf2 (nuclear) | Direct chromatin binding | Nuclear translocation under stress → ARE → antioxidante expressao genica (~1,000 genes)[3] |
Nuclear Translocation
Under metabolic stress (glucose restriction, estresse oxidativo), MOTS-c translocates from mitochondria/cytoplasm para o(a) nucleus. It lacks a canonical nuclear localization signal (NLS) — instead relying on its hydrophobic core for entry. Once nuclear, it binds chromatin at ARE via Nrf2 transcricao factor para regular antioxidante expressao genica.[3]
SIRT1/PGC-1α Pathway
MOTS-c aumenta intracellular NAD+ → ativa SIRT1 → PGC-1α deacetilacao → biogenese mitocondrial and anti-inflamatorio(a) cytokine regulacao.[6]
MAPK/ERK (Tissue-Dependent)
- Adipose tissue: Activates ERK → UCP1/PGC-1α → thermogenesis/browning of white fat[9]
- Inflammation: Inhibits ERK/JNK/p38 → suprime NF-κB[10]
TGF-β/SMAD (Bone)
In osteoblastos: upregula TGF-β1/2 and SMAD7 → Type I sintese de colageno → osteogenic diferenciacao.[11]
