Histone Deacetylases: Deacetylases that remove N-acetyl groups from amino side chains of the amino acids of Histones. The enzyme family can be divided into at least three structurally-defined subclasses. Class I and class Ii deacetylases utilize a zinc-dependent mechanism. The sirtuin histone deacetylases belong to class Iii and are NAD-dependent enzymes.

Chromatin Immunoprecipitation

JoVE Science Education

Histones are proteins that help organize DNA in eukaryotic nuclei by serving as “scaffolds” around which DNA can be wrapped, forming a complex called “chromatin”. These proteins can be modified through the addition of chemical groups, and these changes affect gene expression. Researchers use a technique called chromatin immunoprecipitation (ChIP) to better understand which DNA regions associate with specific histone modifications or other gene regulatory proteins. Antibodies are used to isolate the protein of interest, and the bound DNA is extracted for analysis. Here, JoVE presents the principles behind ChIP, discussing specific histone modifications and their relationship to gene expression and DNA organization. We then review how to perform a ChIP protocol, and explore the ways scientists are currently using this technique.
