Histone modifications - Abcam
At least nine different types of histone modifications have been discovered. Acetylation, methylation, phosphorylation, and ubiquitylation are the most well-understood, while GlcNAcylation, citrullination, crotonylation, sumoylation, and isomerization are more recent discoveries that have yet to be thoroughly investigated.

Histone Modification Table - Cell Signaling Technology
The nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), and linker histone H1 are the primary building blocks of chromatin. Originally thought to function as a static scaffold for DNA packaging, histones have more recently been shown to be dynamic proteins, undergoing multiple types of post-translational modifications that regulate chromatin condensation and DNA ...

Histone Modification - an overview | ScienceDirect Topics
2.2 Histone modification. Histone modification is a fundamental epigenetic regulator that plays a crucial role in various essential cellular processes. This process involves the modification of histone proteins through several types of chemical changes, including acetylation, methylation, phosphorylation, and ubiquitination, which commonly occur on the amino-terminal tails of histone proteins ...

Histone Modifications - What is Epigenetics?
A histone modification is a covalent post-translational modification (PTM) to histone proteins which includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation. The PTMs made to histones can impact gene expression by altering chromatin structure or recruiting histone modifiers. Histone proteins act to package DNA, which wraps around the eight histones, into chromosomes ...

Covalent Histone Modification- Definition, Types, Functions - Microbe Notes
Covalent Histone Modification. The most common types of post-translational chemical modifications of histone are described below. Acetylation. Each of the histone proteins making up the nucleosome core contains a flexible N- terminus of 11-37 amino acid residues extending from the fixed structure of the nucleosome i.e N- termini are known as histone tails (Hayes JJ 2001).

Histone Modifications Guide - Active Motif
It has long been known that the histones are subject to a variety of post-translational modifications (phosphorylation, acetylation, ubiquitylation, methylation: two different types – arginine and lysine) and that these modifications play important roles in chromatin structure and function.
