功能 |
Histone methyltransferase that specifically mono- and dimethylates 'Lys-9' of histone H3 (H3K9me1 and H3K9me2, respectively) in euchromatin. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting HP1 proteins to methylated histones. Also mediates monomethylation of 'Lys-56' of histone H3 (H3K56me1) in G1 phase, leading to promote interaction between histone H3 and PCNA and regulating DNA replication. Also weakly methylates 'Lys-27' of histone H3 (H3K27me). Also required for DNA methylation, the histone methyltransferase activity is not required for DNA methylation, suggesting that these 2 activities function independently. Probably targeted to histone H3 by different DNA-binding proteins like E2F6, MGA, MAX and/or DP1. May also methylate histone H1. In addition to the histone methyltransferase activity, also methylates non-histone proteins: mediates dimethylation of 'Lys- 373' of p53/TP53. Also methylates CDYL, WIZ, ACIN1, DNMT1, HDAC1, ERCC6, KLF12 and itself.

總結(jié) |
G9a, also known as Euchromatic histone?lysine N?methyltransferase 2 (EHMT2), is a member of a family of histone lysine methyltransferases. Recombinant G9a can mono?, di??and tri?methylate histone H3 on Lys9 and Lys27 in?vitro. However, in?vivo G9a forms a complex with GLP, a G9a?related histone methyltransferase, and together these proteins?function as the major euchromatic histone H3 Lys9 mono? and di?methyltransferases, creating transcriptionally repressive marks that facilitate gene silencing. G9a methylates itself on Lys165, a modification that regulates?the association of HP1?repressor proteins?with the G9a/GLP?complex. The G9a/GLP complex also contains Wiz, a zinc finger protein?that is required for G9a/GLP?hetero?dimerization and complex stability. Wiz contains two CtBP?co?repressor binding sites, which mediate?the association of the G9a/GLP with the CtBP?co?repressor complex. In addition, G9a and GLP?are components of other large transcriptional?co?repressor complexes, such as those involving E2F6 and CDP/cut. G9a interacts with DNMT1, and both proteins?are required for methylation of DNA and histone H3 (Lys9) at replication foci, providing a functional?link?between histone H3 Lys9 and CpG?methylation during DNA?replication. G9a activity is critical for meiotic prophase progression, as mutant mice deficient in germ?line G9a show a large loss of mature gametes. In addition, G9a facilitates increased global?levels of di?methyl?histone H3 (Lys9) during hypoxic stress and increased G9a expression is associated with hepatocellular carcinoma.
