Histone-lysine N-methyltransferase KMT5B is an enzyme that in humans is encoded by the KMT5B gene. [5] [6] [7] The enzyme along with WHSC1 is responsible for dimethylation of lysine 20 on histone H4 in mouse and humans. [8] [9]
This gene encodes a protein that contains a SET domain. SET domains appear to be protein-protein interaction domains that mediate interactions with a family of proteins that display similarity with dual-specificity phosphatases (dsPTPases). Two alternatively spliced transcript variants have been found for this gene. [7]
Mutations of the KMT5B gene cause autosomal dominant intellectual developmental disorder 51, a condition first described in 2017 by Stessman et al. [10]
Histone H4 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H4 is involved with the structure of the nucleosome of the 'beads on a string' organization. Histone proteins are highly post-translationally modified. Covalently bonded modifications include acetylation and methylation of the N-terminal tails. These modifications may alter expression of genes located on DNA associated with its parent histone octamer. Histone H4 is an important protein in the structure and function of chromatin, where its sequence variants and variable modification states are thought to play a role in the dynamic and long term regulation of genes.
Histone H3.3 is a protein that in humans is encoded by the H3F3A and H3F3B genes. It plays an essential role in maintaining genome integrity during mammalian development.
DNA (cytosine-5)-methyltransferase 3A (DNMT3A) is an enzyme that catalyzes the transfer of methyl groups to specific CpG structures in DNA, a process called DNA methylation. The enzyme is encoded in humans by the DNMT3A gene.
Histone-lysine N-methyltransferase SETDB1 is an enzyme that in humans is encoded by the SETDB1 gene. SETDB1 is also known as KMT1E or H3K9 methyltransferase ESET.
DNA methyltransferase 1-associated protein 1 is an enzyme that in humans is encoded by the DMAP1 gene.
Histone cluster 2, H3, pseudogene 2, also known as HIST2H3PS2, is a human gene.
Euchromatic histone-lysine N-methyltransferase 2 (EHMT2), also known as G9a, is a histone methyltransferase enzyme that in humans is encoded by the EHMT2 gene. G9a catalyzes the mono- and di-methylated states of histone H3 at lysine residue 9 and lysine residue 27.
