Repression domain of the yeast global repressor Tup1 interacts directly with histones H3 and H4.

Abstract excerpt

Repression of yeast a cell-specific genes by the global repressor Ssn6/Tup1 has been linked to a specific organization of chromatin. We report here that Tup1 directly interacts with the amino-terminal tails of histones H3 and H4, providing a molecular basis for this connection. This interaction appears to be required for Tup1 function because amino-terminal mutations in H3 and H4 that weaken interactions with...
