Yta7, a chromatin segregase regulated by the cell cycle machinery

We have recently revealed the existence of a cell cycle-regulated chromatin segregase, Yta7 (Yeast Tat-binding Analog 7), involved in chromosome replication. Phosphorylation of Yta7 by S-CDK (S-phase Cyclin-Dependent Kinase) regulates its function. These findings link the cell cycle to chromatin biology and suggest how chromatin-modifying enzymes become S phase-specific.
