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.

COP9 subunits 4 and 5 target soluble guanylyl cyclase α1 and p53 in prostate cancer cells.

Bhansali M, Shemshedini L

Our laboratory previously has identified soluble guanylyl cyclase α1 (sGCα1) as a direct target of androgen receptor and essential for prostate cancer cell growth via a pathway independent of nitric oxide (NO) signaling. We identified the COP9 signalosome subunit 4 (CSN4) as a novel interacting partner for sGCα1. Importantly, the CSN4-sGCα1 interaction inhibits sGCα1 proteasomal degradation. Consistent with this, disruption ... [more]
