Previous GeneCards Identifiers for ING3 Gene
The protein encoded by this gene is similar to ING1, a tumor suppressor protein that can interact with TP53, inhibit cell growth, and induce apoptosis. This protein contains a PHD-finger, which is a common motif in proteins involved in chromatin remodeling. This gene can activate p53 trans-activated promoters, including promoters of p21/waf1 and bax. Overexpression of this gene has been shown to inhibit cell growth and induce apoptosis. Allelic loss and reduced expression of this gene were detected in head and neck cancers. Two alternatively spliced transcript variants encoding different isoforms have been observed.

GeneCards Summary for ING3 Gene
ING3 (Inhibitor Of Growth Family, Member 3) is a Protein Coding gene. Diseases associated with ING3 include squamous cell carcinoma, head and neck and breast adenoma. Among its related pathways are Chromatin organization and Senescence and Autophagy. GO annotations related to this gene include histone acetyltransferase activity and methylated histone binding. An important paralog of this gene is ING4.
UniProtKB/Swiss-Prot for ING3 Gene
Component of the NuA4 histone acetyltransferase (HAT) complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair. NuA4 may also play a direct role in DNA repair when directly recruited to sites of DNA damage. Component of a SWR1-like complex that specifically mediates the removal of histone H2A.Z/H2AFZ from the nucleosome.
