KAT5

(redirected from TIP60)

KAT5

A gene on chromosome 11q13 that encodes a catalytic subunit of the NuA4 histone acetyltransferase complex (NuA4 HAC) involved in transcriptional activation of genes, principally by acetylating nucleosomal histones H4 and H2A. The NuA4 HAC may be required for activating transcription programmes of oncogene and proto-oncogene mediated growth induction, tumour suppressor-mediated growth arrest/replicative senescence, apoptosis, and DNA repair. Post-translational modifications include sumoylation, phosphorylation, ubiquination and autoacetylation.

Among the most active HATs in mammals are found cAMP response-element binding protein (CREB) binding protein (CBP), p300, p300/CREB binding protein-associated factor (PCAF), and HIV Tat interactive 60-kDa protein (Tip60).

A number of chromatin-remodeling complexes contain Ruvbl1, like INO80 complex, TIP60 complex, and SWR1 complex, to facilitate the assembling and maintenance of the catalytic activity of ATPase [36, 38, 44].
HAT complexes of the MYST family are named after the four founding family members, MOZ, Ybf2 (Sas3), Sas3, and Tip60 [60, 61].

Sirt1 physically interacts with Tip60 and negatively regulates Tip60-mediated acetylation of H2AX.
HDAC2 was generously provided by Ito Kazuhiro (Imperial College London), and PCAF, HMUF, and TIP60 were kindly provided by Bertrand Joseph (Karolinska Institutet) (see Supplemental Material, "Plasmids").
Additionally, TRIM 29 has been shown to interact with the p53 pathway, either by a direct interaction with p53 itself (46) and/or by interacting with the Tat-interacting protein 60 (Tip60), resulting in suppression of p53 activity.
Based on sequence conservation within the HAT domain and substrate (histone) specificity, nuclear HATs can be grouped into four different families, Gcn5/PCAF (includes yeast Gcn5 and its human ortholog, PCAF), MYST (includes MOZ, Ybf2/Sas3, Sas2, and Tip60), p300/CBP (includes human paralogs p300 and CBP), and Rtt109 (named for regulator of Ty1 transposition gene product 109) [3, 34].
