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.

Heart ischemia results in connexin43 ubiquitination localized at the intercalated discs.

Martins-Marques T, Catarino S, Marques C, Matafome P, Ribeiro-Rodrigues T, Baptista R, Pereira P, Girao H

Efficient electric activation and action potential propagation in the heart largely depends on gap junction (GJ) channels, formed by connexins (Cx) localized at the intercalated discs (IDs). Therefore, fine-tuning and maintenance of GJ in cardiomyocytes is essential for normal heart function. Several mechanisms have been implicated in the regulation of the amount of Cx43Â at the plasma membrane. Results from our ... [more]
