KAT5

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.

Interaction

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, PubMed:29174981). KAT5/TIP60, EPC1, and ING3 together constitute a minimal HAT complex termed Piccolo NuA4. The NuA4 complex interacts with MYC (PubMed:12776177). Interacts with ATM (PubMed:16141325). Interacts with JADE1 (PubMed:15502158). Interacts with PLA2G4A/CPLA2, EDNRA and HDAC7 (PubMed:11416127, PubMed:11262386, PubMed:12551922). Interacts with the cytoplasmic tail of APP and APBB1/FE65 (PubMed:33938178). Interacts with TRIM24 and TRIM68 (PubMed:18451177, PubMed:19909775). 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, PubMed:24835996). Interacts with ZBTB49 (PubMed:25245946). Interacts with SRF (By similarity). Interacts with ATF3; promoting autoacetylation and deubiquitination by USP7 (PubMed:25865756). Interacts with EP300/p300; interaction promotes KAT5 autoacetylation (PubMed:24835996). Interacts with PRKDC; interaction is impaired following KAT5 sumoylation (PubMed:32832608). (Microbial infection) Interacts with HIV-1 TAT.
