Gene

HTA1

Organism
Coccidioides immitis (strain RS) (Valley fever fungus)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi
  1. Functioni

    Core component of nucleosome which plays a central role in DNA double strand break (DSB) repair. 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.

    Post-translational modificationi

    Phosphorylated to form H2AS128ph (gamma-H2A) in response to DNA double-strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks. Phosphorylation is dependent on the DNA damage checkpoint kinases MEC1/ATR and TEL1/ATM, spreads on either side of a detected DSB site and may mark the surrounding chromatin for recruitment of proteins required for DNA damage signaling and repair. Gamma-H2A is removed from the DNA prior to the strand invasion-primer extension step of the repair process and subsequently dephosphorylated. Dephosphorylation is necessary for efficient recovery from the DNA damage checkpoint By similarity.By similarity

    Interactioni

    Subunit structurei

    The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.

    Caution

    To ensure consistency between histone entries, we follow the 'Brno' nomenclature for histone modifications, with positions referring to those used in the literature for the 'closest' model organism. Due to slight variations in histone sequences between organisms and to the presence of initiator methionine in UniProtKB/Swiss-Prot sequences, the actual positions of modified amino acids in the sequence generally differ. In this entry the following conventions are used: H2AK4ac = acetylated Lys-5; H2AK7ac = acetylated Lys-9; H2AS128ph = phosphorylated Ser-130.Curated
