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.

Distinct aerobic and hypoxic mechanisms of HIF-alpha regulation by CSN5.

Bemis L, Chan DA, Finkielstein CV, Qi L, Sutphin PD, Chen X, Stenmark K, Giaccia AJ, Zundel W

Mammalian oxygen homeostasis is dependent on the HIF family of transcription factors. The CSN subunit, CSN5, binds both the CODD of HIF-1 alpha and the pVHL tumor suppressor. High CSN5 expression generates a pVHL-independent form of CSN5 that stabilizes HIF-1 alpha aerobically by inhibiting HIF-1 alpha prolyl-564 hydroxylation. Aerobic CSN5 association with HIF-1 alpha occurs independently of the CSN holocomplex, ... [more]
