Previous GeneCards Identifiers for H2AFY2 Gene
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene encodes a replication-independent histone that is a member of the histone H2A family. It replaces conventional H2A histones in a subset of nucleosomes where it represses transcription and may participate in stable X chromosome inactivation. [provided by RefSeq, Oct 2015]
GeneCards Summary for H2AFY2 Gene
H2AFY2 (H2A Histone Family, Member Y2) is a Protein Coding gene. Among its related pathways are RNA Polymerase I Promoter Opening. GO annotations related to this gene include protein heterodimerization activity and RNA polymerase II regulatory region sequence-specific DNA binding. An important paralog of this gene is H2AFY.
UniProtKB/Swiss-Prot for H2AFY2 Gene
Variant histone H2A which replaces conventional H2A in a subset of nucleosomes where it represses transcription. 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 stable X chromosome inactivation.
