POB3

FACT complex subunit POB3, L000003326, YML069W
Subunit of the heterodimeric FACT complex (Spt16p-Pob3p); FACT associates with chromatin via interaction with Nhp6Ap and Nhp6Bp, and reorganizes nucleosomes to facilitate access to DNA by RNA and DNA polymerases; protein abundance increases in response to DNA replication stress

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.

TAP-MS analysis of FACT interactions and regulation by a ubiquitin ligase, San1.

Barman P, Chakraborty P, Guha S, Kaja A, Bhaumik R, Bhaumik SR

An evolutionarily conserved heterodimeric FACT (Facilitates chromatin transcription) regulates transcription, DNA repair, replication and other cellular processes via its interactions with other proteins. FACT is recently found to be regulated via ubiquitylation and 26S proteasomal degradation, alteration of which is associated with aberrant transcription and genome integrity. However, there has not been a systematic study to analyze FACT interactions proteome-wide ... [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.
