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.

ABIN1 protein cooperates with TAX1BP1 and A20 proteins to inhibit antiviral signaling.

Gao L, Coope H, Grant S, Ma A, Ley SC, Harhaj EW

Upon virus infection, the innate immune response provides the first line of protection and rapidly induces type I interferons (IFNα/β), which mediate potent antiviral effects. To maintain homeostasis and prevent autoimmunity, IFN production is tightly regulated; however, the mechanisms of negative regulation are poorly understood. Herein, we demonstrate that the A20 binding inhibitor of NF-κB 1 (ABIN1) is a novel ... [more]
