Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Casein kinase 2-dependent phosphorylation of human Rad9 mediates the interaction between human Rad9-Hus1-Rad1 complex and TopBP1.

Takeishi Y, Ohashi E, Ogawa K, Masai H, Obuse C, Tsurimoto T

The checkpoint clamp Rad9-Hus1-Rad1 (9-1-1) is loaded by the Rad17-RFC complex onto chromatin after DNA damage and plays a key role in the ATR-dependent checkpoint activation. Here, we demonstrate that in vitro casein kinase 2 (CK2) specifically interacts with human 9-1-1 and phosphorylates serines 341 and 387 (Ser-341 and Ser-387) in the C-terminal tail of Rad9. Interestingly, phosphorylated Ser-387 has ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
