| Specific Function | Involved in the dephosphorylation of the large subunit of RNA polymerase II. Is required in late G1 for normal G1 cyclin expression, bud initiation and expression of certain genes that are periodically expressed during late G1. Associates with the SAP proteins in a cell cycle-dependent manner. |
