MH2A1 also known as macroH2A1 is a histone variant with a distinguished structure characterized by an extended C-terminal macro domain. It has a molecular mass of approximately 42-45 kDa. This histone variant is widely expressed across various tissues showing particularly high levels in differentiated cells. mH2A1 incorporates into chromatin impacting nucleosome stability and chromatin dynamics. Researchers have also identified an isoform known as H2AFY which further highlights the structural complexity and versatile roles of mH2A1 in cellular regulation.
Biological function summary

MH2A1 plays significant roles in chromatin remodeling and gene expression regulation. It is part of the nucleosome replacing canonical histone H2A and influencing the accessibility of chromatin to transcriptional machinery. Through this function mH2A1 can repress or activate gene expression depending on cellular context and interacting partners. Its incorporation into chromatin is associated with the silencing of certain genomic regions such as inactive X chromosome in females with potential implications for epigenetic modifications and cellular differentiation.

Pathways

MH2A1 is notably involved in pathways regulating chromatin organization and cell differentiation. It plays a role in the Polycomb Repressive Complex 2 (PRC2) pathway affecting histone methylation and gene silencing. Furthermore mH2A1 interacts with proteins like EZH2 in PRC2 which carry out methylation at histone H3 on lysine 27. These interactions highlight mH2A1's involvement in maintaining repressive chromatin states and controlling gene expression patterns important for normal cell function.

MH2A1 is connected with cancer and metabolic diseases. Its altered expression has been observed in various cancers where it might impact tumor progression by modulating genes linked to proliferation and differentiation. mH2A1 influences pathways shared with proteins like BRAC1 that are involved in DNA repair processes. Additionally changes in mH2A1 expression are linked to metabolic disorders especially those affecting lipid metabolism and insulin responses suggesting its potential role in regulating metabolic pathways and influencing disease progression.

靶点信息

Variant histone H2A which replaces conventional H2A in a subset of nucleosomes where it represses transcription (PubMed : 12718888, PubMed : 15621527, PubMed : 16428466). Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template (PubMed : 15897469). Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability (PubMed : 15897469). DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Involved in stable X chromosome inactivation (PubMed : 15897469). Inhibits the binding of transcription factors, including NF-kappa-B, and interferes with the activity of remodeling SWI/SNF complexes (PubMed : 12718888, PubMed : 16428466). Inhibits histone acetylation by EP300 and recruits class I HDACs, which induces a hypoacetylated state of chromatin (PubMed : 16107708, PubMed : 16428466).. Isoform 1. Isoform that specifically binds poly-ADP-ribose and O-acetyl-ADP-ribose and plays a key role in NAD(+) metabolism (PubMed : 15902274). Able to bind to the ends of poly-ADP-ribose chains created by PARP1 and cap them (By similarity). This prevents PARP1 from further addition of ADP-ribose and thus limits the consumption of nuclear NAD(+), allowing the cell to maintain proper NAD(+) levels in both the nucleus and the mitochondria to promote proper mitochondrial respiration (By similarity). Increases the expression of genes involved in redox metabolism, including SOD3 (PubMed : 23022728).. Isoform 2. In contrast to isoform 1, does not bind poly-ADP-ribose (PubMed : 15902274). Represses SOD3 gene expression (PubMed : 23022728).
