Gene Name KAT2A
Protein Type Enzyme
Biological Properties
General Function Involved in N-acetyltransferase activity
Specific Function Functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Acetylation of histones gives a specific tag for epigenetic transcription activation. Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. In case of HIV-1 infection, it is recruited by the viral protein Tat. Regulates Tat's transactivating activity and may help inducing chromatin remodeling of proviral genes. Component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4.
Pathways
  • Human T-cell leukemia virus 1 infection
  • Notch signaling pathway
  • Viral carcinogenesis
