Something about silencing protein 5

UniProtKB accession:  Q99314

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the SAS complex, a multiprotein complex that acetylates 'Lys-16' of histone H4 and 'Lys-14' of histone H3. The SAS complex is however unable to acetylate nucleosomal histones. The complex is involved in transcriptional silencing at telomeres and at HML locus. Also involved in rDNA silencing. In the complex, SAS5 is required for maximal histone acetyltransferase (HAT) activity of the complex, suggesting that it may be required to stabilize the complex or help in substrate recognition.
