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 (PubMed:12776177, PubMed:15042092, PubMed:15121871, PubMed:15310756, PubMed:14966270, PubMed:16387653, PubMed:19909775, PubMed:15196461). This modification may both alter nucleosome-DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription (PubMed:12776177, PubMed:15042092, PubMed:15121871, PubMed:15310756, PubMed:14966270, PubMed:15196461). 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 (PubMed:15196461). NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage (PubMed:15196461). Component of a SWR1-like complex that specifically mediates the removal of histone H2A.Z/H2AZ1 from the nucleosome (PubMed:24463511). Also acetylates non-histone proteins, such as ATM, NR1D2, RAN, FOXP3, ULK1 and RUBCNL/Pacer (PubMed:16141325, PubMed:17360565, PubMed:17996965, PubMed:29040603, PubMed:30704899). Directly acetylates and activates ATM (PubMed:16141325). Relieves NR1D2-mediated inhibition of APOC3 expression by acetylating NR1D2 (PubMed:17996965). Promotes FOXP3 acetylation and positively regulates its transcriptional repressor activity (PubMed:17360565). Acetylates RAN at 'Lys-134' (PubMed:29040603). Together with GSK3 (GSK3A or GSK3B), acts as a regulator of autophagy: phosphorylated at Ser-86 by GSK3 under starvation conditions, leading to activate acetyltransferase activity and promote acetylation of key autophagy regulators, such as ULK1 and RUBCNL/Pacer (PubMed:30704899).

Post Translational Modifications: (Microbial infection) In case of HIV-1 infection, interaction with the viral Tat protein leads to KAT5 polyubiquitination and targets it to degradation.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.Ubiquitinated by MDM2, leading to its proteasome-dependent degradation.Phosphorylated on Ser-86 and Ser-90; enhanced during G2/M phase (PubMed:12468530). The phosphorylated form has a higher histone acetyltransferase activity (PubMed:12468530). Phosphorylation at Ser-86 by GSK3 (GSK3A or GSK3B) activates acetyltransferase activity (PubMed:30704899). Phosphorylation at Ser-90 is a prerequisite for phosphorylation at Ser-86 by GSK3 (PubMed:30704899).Autoacetylation at Lys-327 is required for proper function.

Subcellular Location: Nucleus. Nucleus>Nucleolus. Cytoplasm>Perinuclear region. Note: Upon stimulation with EDN1, it is exported from the nucleus to the perinuclear region and UV irradiation induces translocation into punctuate subnuclear structures named nuclear bodies.

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 (PubMed:12963728, PubMed:10966108, PubMed:15196461, PubMed:14966270). HTATTIP/TIP60, EPC1, and ING3 together constitute a minimal HAT complex termed Piccolo NuA4. The NuA4 complex interacts with MYC. Interacts with ATM (PubMed:16141325). Interacts with JADE1 (PubMed:15502158). Interacts with PLA2G4A/CPLA2, EDNRA and HDAC7 (PubMed:11416127, PubMed:11262386, PubMed:12551922).

Forms a complex with SENP6 and UBE2I in response to UV irradiation. Identified in a complex with HINT1 (PubMed:16835243). Interacts with ATF2 and CUL3 (PubMed:18397884). Interacts with NR1D2 (via N-terminus) (PubMed:17996965). Component of a SWR1-like complex (PubMed:24463511). Interacts with FOXP3 (PubMed:17360565).

NCBI Description

The protein encoded by this gene belongs to the MYST family of histone acetyl transferases (HATs) and was originally isolated as an HIV-1 TAT-interactive protein. HATs play important roles in regulating chromatin remodeling, transcription and other nuclear processes by acetylating histone and nonhistone proteins. This protein is a histone acetylase that has a role in DNA repair and apoptosis and is thought to play an important role in signal transduction. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]
