Affinity Capture-RNA

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and associated RNA species identified by Northern blot, RT-PCR, affinity labeling, sequencing, or microarray analysis.

Association of yeast Upf1p with direct substrates of the NMD pathway.

Johansson MJ, He F, Spatrick P, Li C, Jacobson A

Nonsense-mediated mRNA decay (NMD) is a surveillance mechanism that detects and degrades transcripts containing premature translation termination codons. Gene expression profiling experiments have shown that inactivation of the NMD pathway leads to the accumulation of both aberrant, nonsense-containing mRNAs, and many apparently wild-type transcripts. Such increases in transcript steady-state levels could arise from direct changes in the respective mRNA half-lives, ... [more]

Throughput

  • High Throughput

Additional Notes

  • Transcript signal intensity, between the Upf1p-TAP and mock samples, showed a relative change of at least 2-fold. This change was reproducible in at least three of four replicate experiments and demonstrated a statistically significant P value.

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.
