DNA-Binding Peptide
DNA-Binding Peptide — A peptide designed to interact with specific DNA sequences through electrostatic or groove-binding interactions, used in gene regulation research.
What Is a DNA-Binding Peptide?
DNA-binding peptides are short sequences that bind double- or single-stranded DNA through electrostatic interactions between cationic residues (Lys, Arg) and the polyanionic DNA backbone, or through minor/major groove recognition. DNA-binding peptides are used for gene delivery, transcription modulation, and as components of artificial nucleases.
Examples
- NLS peptides: Lys/Arg-rich sequences bind DNA and facilitate nuclear import
- Condensing peptides: Compact DNA into nanoparticles for transfection
- AT-hook: RGRP motif binds AT-rich minor groove of DNA
