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.

Ssf1p prevents premature processing of an early pre-60S ribosomal particle.

Fatica A, Cronshaw AD, Dlakic M, Tollervey D

Ssf1p and Ssf2p are two nearly identical and functionally redundant nucleolar proteins. In the absence of Ssf1p and Ssf2p, the 27SA(2) pre-rRNA was prematurely cleaved, inhibiting synthesis of the 27SB and 7S pre-rRNAs and the 5.8S and 25S rRNA components of the large ribosomal subunit. On sucrose gradients, Ssf1p sedimented with pre-60S ribosomal particles. The 27SA(2), 27SA(3), and 27SB pre-rRNAs ... [more]

Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Negative Genetic

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.
