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.

AMSH-mediated deubiquitination of Cx43 regulates internalization and degradation of gap junctions.

Ribeiro-Rodrigues TM, Catarino S, Marques C, Ferreira JV, Martins-Marques T, Pereira P, Girao H

Gap junctions (GJs) are specialized cell-cell contacts formed by connexins (Cxs), which provide direct intercellular communication between eukaryotic cells. Although Cx43 has long been known to be a substrate for ubiquitination, the reversal of this modification by deubiquitylases (DUBs) has never been described. Here we report that the DUB-associated molecule with the SH3 domain of STAM (AMSH) interacts with Cx43 ... [more]

Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.
