- In biology,
histones are
highly basic proteins abundant in
lysine and
arginine residues that are
found in
eukaryotic cell
nuclei and in most
Archaeal phyla...
-
eight proteins called histones,
which are
known as a
histone octamer. Each
histone octamer is
composed of two
copies each of the
histone proteins H2A, H2B...
-
proteins which remain after the
histones have been removed, are
classified as non-
histone proteins. The non-
histone proteins, are a
large group of heterogeneous...

Examples of
mechanisms that
produce such
changes are DNA
methylation and
histone modification, each of
which alters how
genes are
expressed without altering...
-
Histone methyltransferases (HMT) are
histone-modifying
enzymes (e.g.,
histone-lysine N-methyltransferases and
histone-arginine N-methyltransferases),...
-
Histone variants are
proteins that
substitute for the core
canonical histones (H3, H4, H2A, H2B) in
nucleosomes in
eukaryotes and
often confer specific...

Histone acetylation and
deacetylation are the
processes by
which the
lysine residues within the N-terminal tail
protruding from the
histone core of the...
-
Histone methylation is a
process by
which methyl groups are
transferred to
amino acids of
histone proteins that make up nucleosomes,
which the DNA double...

Histone H1 is one of the five main
histone protein families which are
components of
chromatin in
eukaryotic cells.
Though highly conserved, it is nevertheless...
- both
histone and non-
histone proteins.
HDACs allow histones to wrap the DNA more tightly. This is
important because DNA is
wrapped around histones, and...
