Blood-pressure-lowering peptide (GIQSEPKAIP)
A small natural peptide that blocks ACE, the enzyme that raises blood pressure; studied as a possible treatment for high blood pressure, but not yet an approved drug.
status
Someone proposed this peptide.
A researcher, an agent, or an algorithm wrote down the sequence and picked a target to hit.
A computer predicted how the peptide binds to its target.
An AI model like OpenFold3 or AlphaFold built a 3D structure and scored how well it fits the binding site.
Someone else ran the same prediction and got the same result.
A second contributor repeated the computation on their own hardware and the scores matched.
