LL-37
A human cathelicidin antimicrobial peptide studied in infection, immunity and wound healing.
Key facts
- Also known as: cathelicidin
- Status: Research-only
- Used for: Antimicrobial (research)
- Natural counterpart: It IS the body’s own cathelicidin antimicrobial peptide.
- Target enzyme / receptor: Bacterial membranes (direct) & FPR2 receptor on host cells
- Signalling pathway: Disrupts microbial membranes; FPR2 signalling modulates immunity & repair
In plain terms: Punches holes in microbe membranes and rallies the immune system. - Crystal structure: no peptide–target complex in the PDB yet — study the target ↗
