Target

  • Function

    Acetylates soluble but not nucleosomal histone H4 at 'Lys-5' (H4K5ac) and 'Lys-12' (H4K12ac) and, to a lesser extent, acetylates histone H2A at 'Lys-5' (H2AK5ac). Has intrinsic substrate specificity that modifies lysine in recognition sequence GXGKXG. May be involved in nucleosome assembly during DNA replication and repair as part of the histone H3.1 and H3.3 complexes. May play a role in DNA repair in response to free radical damage.
  • Sequence similarities

    Belongs to the HAT1 family.
  • Developmental stage

    Highly expressed in mitotic cells (at protein level).
  • Cellular localization

    Nucleus matrix and Cytoplasm. Nucleus. Nucleus matrix. Nucleus > nucleoplasm. Localization is predominantly nuclear in normal cells. Treatment with hydrogen peroxide or ionizing radiation enhances nuclear localization through redistribution of existing protein.

    ab194296 was shown to recognize KAT1/HAT1 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when KAT1/HAT1 knockout samples were examined. Wild-type and KAT1 / HAT1 knockout samples were subjected to SDS-PAGE. Ab194296 and ab18058 (loading control to GAPDH) were diluted at 1/1000 and 1/10,000 dilution respectively and incubated overnight at 4oC. Blots were developed with IRDye® 800CW Goat anti-Rabbit IgG (H + L) and IRDye® 680 Goat anti-Mouse IgG (H + L) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
