SHLP1

also known as: Small Humanin-Like Peptide 1, SHLP-1

The first small humanin-like peptide — a mitochondrial-derived signaling molecule with chaperone-like cytoprotective activity.

A mitochondrial-derived peptide encoded within the MT-RNR2 gene that exhibits chaperone-like cytoprotective activity, protecting cells from oxidative stress and apoptosis.

Mechanism of action

Encoded within the 16S rRNA gene (MT-RNR2) of mitochondrial DNA. Demonstrates chaperone-like activity, stabilizing protein folding under stress conditions.

Primary uses

  • Research: mitochondrial-derived peptide biology
  • Cytoprotection research
  • Aging and neurodegeneration research

Typical dosing

N/A N/A N/A (research only)

No established dosing.

Regulatory status

Not approved. Early-stage research peptide in the emerging MDP field.

Related peptides

SHLP2

A 26-aa mitochondrial-derived peptide, the most-studied of the SHLP1–SHLP6 family (Cohen lab, USC). Preclinical data report insulin-sensitizing, antiapoptotic, and metabolic-protective effects; lower plasma levels in humans correlate with age and with type 2 diabetes. Research-only; no human clinical trials.

SHLP3

One of the six small humanin-like peptides (Cohen lab); preclinical reports suggest roles in adipogenesis and metabolic regulation. Less well-characterized than SHLP2 or humanin. Research-only.

SHLP6

A SHLP-family member with a notably distinct preclinical profile: where humanin and SHLP2 are antiapoptotic, SHLP6 has been reported as pro-apoptotic, suggesting the mitochondrial-derived peptide family includes members with opposing regulatory roles. Research-only.

Humanin

A mitochondrial-derived peptide with neuroprotective, metabolic, and anti-apoptotic activity — one of the first signaling peptides identified as encoded by mitochondrial DNA.

MOTS-c

A mitochondrially encoded peptide studied for its effects on metabolic homeostasis, insulin sensitivity, and exercise capacity.
