H1-2
H1-2 (Histone H1.2) is a gene. The public catalogues list it as a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Diffuse large B-cell lymphoma.
Overview
Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fibre. Histone H1-2 is required for the condensation of nucleosome chains into higher-order structured fibres. Compared to other histone H1 variants, H1-2 plays an essential role in nucleosome condensation: its absence leads to global chromatin decompaction, which is not observed when depleting other histone H1 variants.

Biology
Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fibre. Histone H1-2 is required for the condensation of nucleosome chains into higher-order structured fibres. Compared to other histone H1 variants, H1-2 plays an essential role in nucleosome condensation: its absence leads to global chromatin decompaction, which is not observed when depleting other histone H1 variants. Histone H1-2 also acts as a histone reader: specifically recognises and binds histone H3 trimethylated at 'lys-27' (H3K27me3). Histones H1 also promote formation of the H3K27me3 mark by the PRC2/EED-EZH2 complex, possibly by facilitating restoration of H3K27me3 post-replication. Together with histone H1-3, histone H1-2 acts as a regulator of splicing, most specifically exon skipping and intron retention events: histone H1-2 has a high affinity for exons and regulates splicing by affecting RNA polymerase II (RNAPII) elongation.

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: CIViC holds 1 clinical evidence items on its variants. Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
