KAT5 HTATIP TIP60 Histone acetyltransferase KAT5 60 kDa Tat-interactive protein Histone acetyltransferase HTATIP Lysine acetyltransferase 5 cPLA(2)-interacting protein
Molecular Weight(MW)
58582 Da
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. NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage. Directly acetylates and activates ATM. In case of HIV-1 infection, interaction with the viral Tat protein leads to KAT5 polyubiquitination and targets it to degradation
Tissue Specificity
This KAT5 / Tip60/HTATIP antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 476~505 amino acids from the C-terminal region of human HTATIP.
Cellular Localization
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
Western blot analysis of anti-HTATIP Pab in CEM cell line tissue lysate (35ug/lane).HTATIP(arrow) was detected using the purified Pab (1:60 dilution).
