Ada3

Ada3
PFAM accession number:PF10198
Interpro abstract (IPR019340):

This entry is found in Ada3 and homologous proteins which function as part of histone acetyltransferase complexes [ (PUBMED:8413201) ]. Ada3 is an essential component of the Ada transcriptional coactivator (alteration/deficiency in activation) complex. It plays a key role in linking histone acetyltransferase-containing complexes to p53 (tumour suppressor protein) thereby regulating p53 acetylation, stability and transcriptional activation following DNA damage [ (PUBMED:17272277) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Ada3
