Identifiers, parent molecule, targets and development stage, from curated data.
Colivelin joins ADNF-9 to a modified humanin-derived sequence. Its sequence is SALLRSIPAPAGASRLLLLTGEIDLP. Preclinical studies examine neuroprotection and STAT3-associated signaling. Native humanin and colivelin are distinct.
No molecular target is recorded for this peptide.
Residues, differences from the parent, calculated properties and 3D structure. Source values and calculated values are shown separately.
26 amino acids
Calculated from the two sequences. Curated notes are shown as given.
14 of 19 aligned residues identical (74%) · 5 substitutions · 7 added residues · Humanin 1–19
Differences from the parent
Basis: A modified humanin-derived sequence joins ADNF-9. It is not one contiguous native humanin fragment.
Calculated from the two sequences with @pepdb/chem alignToParent (ungapped unless a gap scores higher). The record’s curated notes are shown as given.
