Recombinant Human Histone H2A.Z protein (denatured) (His tag N-Terminus)

일반 정보

기능

Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. May be involved in the formation of constitutive heterochromatin. May be required for chromosome segregation during cell division.

Belongs to the histone H2A family.

Post-translational modifications

Monoubiquitination of Lys-122 gives a specific tag for epigenetic transcriptional repression.. Acetylated on Lys-5, Lys-8, Lys-12 and Lys-14 by KAT2A; KAT2A is recruited by the XPC complex in absence of DNA damage (PubMed:31527837). Acetylated on Lys-5, Lys-8 and Lys-12 during interphase; acetylation disappears at mitosis (By similarity). Acetylation by the NuA4 histone acetyltransferase complex is required for hematopoietic stem cell maintenance (By similarity).. Monomethylated on Lys-5 and Lys-8 by SETD6. SETD6 predominantly methylates Lys-8, lys-5 being a possible secondary site.. Not phosphorylated.. Lactylated in macrophages by EP300/P300 by using lactoyl-CoA directly derived from endogenous or exogenous lactate, leading to stimulates gene transcription.
