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.

Regulation of interleukin 7-dependent immunoglobulin heavy-chain variable gene rearrangements by transcription factor STAT5.

Bertolino E, Reddy K, Medina KL, Parganas E, Ihle J, Singh H

Rearrangement of immunoglobulin heavy-chain variable (V(H)) gene segments has been suggested to be regulated by interleukin 7 signaling in pro-B cells. However, the genetic evidence for this recombination pathway has been challenged. Furthermore, no molecular components that directly control V(H) gene rearrangement have been elucidated. Using mice deficient in the interleukin 7-activated transcription factor STAT5, we demonstrate here that STAT5 ... [more]
