## TL;DR

HDAC5 (Histone deacetylase 5) is a protein that switches other genes on and off. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Non-Hodgkin lymphoma and Multiple myeloma.

## Summary

In vitro, it deacetylates lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes.

Open Targets scores its association with cancer at 0.61 (direct and indirect evidence; datatypes literature 0.97, genetic association 0.00, clinical 0.95).

- Biology: In vitro, it deacetylates lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Involved in muscle maturation by repressing transcription of myocyte enhancer MEF2C. During muscle differentiation, it shuttles into the cytoplasm, allowing the expression of myocyte enhancer factors. Involved in the MTA1-mediated epigenetic regulation of ESR1 expression in breast cancer. Location: Nucleus; Cytoplasm (UniProt). Locus 17q21.31 (HGNC).
- Where found: Non-Hodgkin lymphoma: Open Targets association 0.56 with non-Hodgkin lymphoma (MONDO_0018908); Multiple myeloma: Open Targets association 0.55 with plasma cell myeloma (MONDO_0009693)

## Notes

- 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: Open Targets known-drug datatype score 0.95. Evidence tier "approved-drug" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
