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. Nucleosomes containing this histone are less rigid and organize less DNA than canonical nucleosomes in vivo. They are enriched in actively transcribed genes and associate with the elongating form of RNA polymerase. They associate with spliceosome components and are required for mRNA splicing. May participate in spermatogenesis. {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}. |Histone| No GO term information is available for this gene. \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp231|Epothilone-B 0.0015μM R05 exp231]]|2.13| ^Gene^Correlation^ |[[:human genes:p:pfdn5|PFDN5]]|0.406| Global Fraction of Cell Lines Where Essential: N/A ^Tissue^Fraction Of Cell Lines Where Essential^ == Essentiality in NALM6 == * **Essentiality Rank**: 5792 * **Expression level (log2 read counts)**: -3.9 {{:chemogenomics:nalm6 dist.png?nolink |}}
