General annotation (Comments)

Function

Catalytic subunit of the NuA4 histone acetyltransferase 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. The NuA4 complex ATPase and helicase activities seem to be, at least in part, contributed by the association of RUVBL1 and RUVBL2 with EP400. NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage. Directly acetylates and activates ATM By similarity.

Catalytic activity

Acetyl-CoA + [histone] = CoA + acetyl-[histone].

Subunit structure

Component of the NuA4 histone acetyltransferase complex which contains the catalytic subunit KAT5/TIP60 and the subunits EP400, TRRAP/PAF400, BRD8/SMAP, EPC1, DMAP1/DNMAP1, RUVBL1/TIP49, RUVBL2, ING3, actin, ACTL6A/BAF53A, MORF4L1/MRG15, MORF4L2/MRGX, MRGBP, YEATS4/GAS41, VPS72/YL1 and MEAF6 By similarity. HTATTIP/TIP60, EPC1, and ING3 together constitute a minimal HAT complex termed Piccolo NuA4 By similarity. The NuA4 complex interacts with MYC By similarity. Interacts with ATM By similarity. Interacts with PHF17 By similarity. Interacts with PLA2G4A/CPLA2, EDNRA and HDAC7 By similarity. Interacts with the cytoplasmic tail of APP and APBB1/FE65 By similarity. Interacts with TRIM24 and TRIM68 By similarity. Forms a complex with SENP6 and UBE2I in response to UV irradiation. Identified in a complex with HINT1 By similarity.

Subcellular location

Nucleus › nucleolus. Cytoplasm › perinuclear region By similarity. Note: Upon stimulation with EDN1, it is exported from the nucleus to the perinuclear region By similarity. Ref.1

Tissue specificity

Expressed in testis, heart, brain, kidney and liver. Weakly expressed in lung. Ref.1

Post-translational modification

Sumoylated by UBE2I at Lys-430 and Lys-451, leading to increase of its histone acetyltransferase activity in UV-induced DNA damage response, as well as its translocation to nuclear bodies By similarity.

Phosphorylated on Ser-86 and Ser-90; enhanced during G2/M phase. Phosphorylated form has a higher activity By similarity.

Ubiquitinated by MDM2, leading to its proteasome-dependent degradation By similarity.

Autoacetylation at Lys-327 is required for proper function By similarity.

Sequence similarities

Belongs to the MYST (SAS/MOZ) family.

Contains 1 C2HC-type zinc finger.
