External Ids for ING4 Gene
This gene encodes a tumor suppressor protein that contains a PHD-finger, which is a common motif in proteins involved in chromatin remodeling. This protein can bind TP53 and EP300/p300, a component of the histone acetyl transferase complex, suggesting its involvement in the TP53-dependent regulatory pathway. Multiple alternatively spliced transcript variants have been observed that encode distinct proteins. [provided by RefSeq, Jul 2008]

ING4 (Inhibitor Of Growth Family, Member 4) is a Protein Coding gene. Among its related pathways are RNA Polymerase I Promoter Opening and RNA Polymerase I Promoter Opening. GO annotations related to this gene include transcription coactivator activity and methylated histone binding. An important paralog of this gene is ING2.
UniProtKB/Swiss-Prot for ING4 Gene
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. Through chromatin acetylation it may function in DNA replication. May inhibit tumor progression by modulating the transcriptional output of signaling pathways which regulate cell proliferation. Can suppress brain tumor angiogenesis through transcriptional repression of RELA/NFKB3 target genes when complexed with RELA. May also specifically suppress loss of contact inhibition elicited by activated oncogenes such as MYC. Represses hypoxia inducible factors (HIF) activity by interacting with HIF prolyl hydroxylase 2 (EGLN1).
