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.

An N-terminal motif unique to primate tau enables differential protein-protein interactions.

Compared with other mammalian species, humans are particularly susceptible to tau-mediated neurodegenerative disorders. Differential interactions of the tau protein with other proteins are critical for mediating tau's physiological functions as well as tau-associated pathological processes. Primate tau harbors an 11-amino acid-long motif in its N-terminal region (residues 18-28), which is not present in non-primate species and whose function is unknown. ... [more]
