Predicted to enable histone H4K16 acetyltransferase activity. Predicted to be involved in double-strand break repair via homologous recombination. Predicted to act upstream of or within DNA repair and regulation of DNA-templated transcription. Predicted to be located in nucleus. Predicted to be part of NuA4 histone acetyltransferase complex. Orthologous to human KAT5 (lysine acetyltransferase 5).
