Domains of Gln3p interacting with karyopherins, Ure2p, and the target of rapamycin protein.

Carvalho J, Zheng XF

Gln3p is a GATA-type transcription factor responsive to the quality of nitrogen and carbon. In preferred nitrogen such as glutamine, Gln3p is phosphorylated and sequestered in the cytoplasm in a manner that is dependent on the target of rapamycin (TOR) protein and Ure2p. In nonpreferred nitrogen or nitrogen starvation, Gln3p is dephosphorylated and imported into the nucleus via karyopherin alpha/Srp1p. ... [more]

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.

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.
