Structural Insights into Linear Tri-ubiquitin Recognition by A20-Binding Inhibitor of NF-κB, ABIN-2.

Lin SM, Lin SC, Hong JY, Su TW, Kuo BJ, Chang WH, Tu YF, Lo YC

Recognition of linear polyubiquitin by specific ubiquitin-binding proteins plays an important role in mediating nuclear factor-κB (NF-κB) signaling. A20 binding proteins, ABINs, recognize linear polyubiquitin and A20 through UBAN and AHD1, respectively, for the inhibition of NF-κB activation. Here we report the crystal structure of the AHD1-UBAN fragment of ABIN2 in complex with linear tri-ubiquitin, which reveals a 2:1 stoichiometry ... [more]

Affinity Capture-Western
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.

Co-crystal Structure
Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
