| Standard Name | Cdc55p 1 |
|---|---|
| Systematic Name | Ygl190cp |
| ORF Classification | Verified |
| Description | Non-essential regulatory subunit B of protein phosphatase 2A (PP2A); localization to the cytoplasm requires Zds1p and Zds2p and promotes mitotic entry; localization to the nucleus prevents mitotic exit; required for correct nuclear division and chromosome segregation in meiosis; maintains nucleolar sequestration of Cdc14p during early meiosis; limits formation of PP2A-Rts1p holocomplexes to ensure timely dissolution of sister chromosome cohesion (2, 3, 4, 5, 6, 7) |
