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 (PubMed:15257289, PubMed:16287874, PubMed:16957777, PubMed:17591702, PubMed:17726088, PubMed:18329190, PubMed:22795134). Nucleosomes containing this histone are less rigid and organize less DNA than canonical nucleosomes in vivo (PubMed:15257289, PubMed:16957777, PubMed:17591702, PubMed:24336483). They are enriched in actively transcribed genes and associate with the elongating form of RNA polymerase (PubMed:17591702, PubMed:24753410). They associate with spliceosome components and are required for mRNA splicing (PubMed:22795134). {ECO:0000269|PubMed:15257289, ECO:0000269|PubMed:16287874, ECO:0000269|PubMed:16957777, ECO:0000269|PubMed:17591702, ECO:0000269|PubMed:17726088, ECO:0000269|PubMed:18329190, ECO:0000269|PubMed:22795134, ECO:0000269|PubMed:24336483, ECO:0000269|PubMed:24753410}. |Histone| |nuclear nucleosome| |transcriptionally active chromatin| |nucleosome assembly| |chromatin assembly| |chromatin assembly or disassembly| |nucleosome organization| |DNA packaging| |protein-DNA complex assembly| |nuclear chromatin| |protein-DNA complex subunit organization| |DNA conformation change| |mRNA processing| |protein heterodimerization activity| |mRNA metabolic process| |chromatin organization| |cellular protein-containing complex assembly| |RNA processing| |chromosome organization| |DNA binding| |protein-containing complex assembly| |RNA metabolic process| |protein-containing complex subunit organization| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp231|Epothilone-B 0.0015μM R05 exp231]]|1.94| ^Gene^Correlation^ |[[:human genes:v:vbp1|VBP1]]|0.4| Global Fraction of Cell Lines Where Essential: N/A ^Tissue^Fraction Of Cell Lines Where Essential^ == Essentiality in NALM6 == * **Essentiality Rank**: 5965 * **Expression level (log2 read counts)**: -2.6 {{:chemogenomics:nalm6 dist.png?nolink |}}
