BIOLOGICAL PROFILE

Mitochondrial Retrograde Signaling

Nuclear-Mitochondrial Crosstalk & Metabolic Regulation

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded by the mitochondrial genome within the 12S ribosomal RNA locus. Historically considered non-coding, mitochondrial short open reading frames (sORFs) produce bioactive signaling peptides termed Mitochondrial-Derived Peptides (MDPs).

Unlike classical nuclear-encoded hormonal peptides, MOTS-c acts as an autonomous retrograde signaling factor. Under metabolic or cellular stress, MOTS-c rapidly translocates to the nucleus where it binds chromatin to regulate adaptive gene transcription networks involved in glucose metabolism, oxidative stress resilience, and sphingolipid homeostasis.

account_tree Primary Molecular Mechanisms

check_circle
AMPK Pathway Activation: Phosphorylates and stimulates AMP-activated protein kinase independently of intracellular AMP/ATP ratios by inhibiting the folate-methionine cycle and generating endogenous AICAR accumulation.
check_circle
GLUT4 Translocation: Triggers rapid translocation of glucose transporter type 4 (GLUT4) to the plasma membrane in skeletal muscle myocytes, augmenting insulin-independent cellular glucose uptake.

Mitochondrial Biogenesis & PGC-1α: Upregulates Peroxisome proliferator-activated receptor gamma coactivator 1-alpha, driving mitochondrial DNA replication and oxidative phosphorylation efficiency.

LABORATORY GUIDELINES

Storage & Reconstitution Protocol

FOR RESEARCH ONLY

ac_unit

1. Lyophilized Storage

Store intact lyophilized vials at -20 °C (-4 °F) for standard preservation up to 24 months. For extended multi-year preservation, store at -80 °C. Protect from moisture and direct ultraviolet exposure.

Stable at 2-8 °C for up to 90 days prior to reconstitution.

science

2. Reconstitution

Allow vial to reach room temperature (20-25 °C) for 30 minutes before puncturing stopper. Introduce sterile Bacteriostatic Water or 0.9% NaCl slowly along the interior glass wall. Do NOT vortex or vigorously agitate. Swirl gently until dissolved.

Avoid foaming or mechanical shearing of peptide chains.

thermostat

3. Reconstituted Storage

Keep reconstituted solution refrigerated at 2 °C to 8 °C (36 °F to 46 °F). If prepared with Bacteriostatic Water (0.9% Benzyl Alcohol), solution remains stable for up to 30 days. If aliquoting is required, store at -20 °C; avoid freeze-thaw cycles.

Do not subject reconstituted solution to repeated freeze/thaws.

warning

Standard Laboratory Safety Notice: This compound is synthesized strictly for in vitro laboratory research, analytical testing, and preclinical assays.
