Mapping Protein- DNA Interactions
with ChIP- Seq
13.1 Principle of ChIP- Seq
Without the involvement of DNA- interacting proteins, the information
coded in DNA cannot be accessed, transcribed, and maintained. Besides a
large number of transcription factors and coactivators, key DNA- interacting
proteins include histones, DNA and RNA polymerases, and enzymes for DNA
repair and modication (e.g., methylation). Through their DNA- interacting
domains, such as helix- turn- helix, zinc nger, and leucine zipper domains,
these proteins interact with their DNA targets by hydrogen bonding, hydro-
phobic interactions, ...
