Problem:Deacetylases for these proteins are recruited by Sin3, which binds to upstream repression sequences in transcriptional regulation. Acetyases like Gcn5 also modify the process of transcription by chemically modifying the lysine rich tails of these, which allows them to function in epigenetic inheritance processes such as imprinting. The 2B, 2A, 3, and 4 varieties are always present in equal amounts, while 1 and 5 varieties are interchangeable. FTP, name these proteins that wind up DNA about themselves to form nucleosomes.
