Protein
Something about silencing protein 4
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
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, SAS4 is essential for histone acetyltransferase (HAT) activity of the complex.
