| UniProt AC | P04911 | |
| Protein Name | Histone H2A.1 | |
| Gene Name | HTA1 | |
| Organism | Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). | |
| Sequence Length | 132 | |
| Subcellular Localization | Nucleus. Chromosome. | |
| Protein Description | 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.. | |
