Research Comparison
KPV (Lys-Pro-Val) vs MOTS-c
A side-by-side research comparison of KPV (Lys-Pro-Val) and MOTS-c drawn from Cobalt Peptides' peptide database records.
KPV (Lys-Pro-Val)
KPV (Lys-Pro-Val) is a tripeptide derived from the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH). Unlike the parent hormone, KPV retains potent anti-inflammatory and immunomodulatory activity without inducing melanogenesis or pigmentation. It has been investigated for its ability to modulate inflammatory pathways at the cellular level, with particular relevance to inflammatory bowel disease, dermatological conditions, and systemic inflammation. Its small size enables efficient cellular penetration and direct interaction with intracellular signaling pathways.
MOTS-c
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid mitochondrial-derived peptide encoded by mitochondrial DNA. It functions as a mitohormone, regulating metabolic homeostasis, insulin sensitivity, and cellular stress responses. Unlike nuclear-encoded peptides, MOTS-c is produced within mitochondria and can translocate to the nucleus under metabolic stress, where it influences gene expression. Its primary activity involves activation of the AMPK pathway via the folate-AICAR axis, making it a key regulator of energy metabolism and mitochondrial function.
