Docking models for 19 short peptides against DNA; some peptides share sites (KE and EDP to agat; KEDW and AED to acct; AEDL and EDL to ctcc) — computational complexes, not wet-lab proof of transcription control.

Editorial summary of a 2016 original article in Bulletin of Experimental Biology and Medicine. Molecular docking of short peptides to DNA. Public pages cite PubMed only. Read the paper: PMID 27909961.

Methods

The authors state that one short peptide can regulate dozens of genes but that the molecular mechanism remains unclear, then suppose nuclear entry and DNA binding. Spatial models of DNA–peptide complexes were constructed for 19 short peptides by docking. Software, DNA fragments, and scoring functions belong in the primary text. This is computation, not a reporter-gene assay.

Findings

Some peptides are assigned the same binding sites: KE (Vilon) and EDP to an agat sequence; KEDW (Pancragen) and AED to acct; AEDL (Bronchogen) and EDL to ctcc.

Docking poses are not evidence that those peptides regulate those genes in cells or in people. Follow the PMID.
