Inhibitor of growth protein 5 (IPR028638)

Short name: ING5

Overlapping homologous superfamilies


Family relationships



Members of the ING (Inhibitor of growth protein) family of tumour suppressors regulate cell cycle progression, apoptosis, and DNA repair as important cofactors of p53. Inhibitor of growth protein 5 (ING5) is a component of the HBO1 complex which has a histone H4-specific acetyltransferase activity, a reduced activity toward histone H3 and is responsible for the bulk of histone H4 acetylation in vivo. It is also a component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity. Through chromatin acetylation ING5 may regulate DNA replication and function as a transcriptional coactivator [PMID: 12750254, PMID: 16387653, PMID: 21750715].
