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.

Wnt controls the transcriptional activity of Kaiso through CK1ε-dependent phosphorylation of p120-catenin.

Del Valle-Perez B, Casagolda D, Lugilde E, Valls G, Codina M, Dave N, de Herreros AG, Dunach M

p120-catenin is an E-cadherin-associated protein that modulates E-cadherin function and stability. In response to Wnt3a, p120-catenin is phosphorylated at Ser268 and Ser269, disrupting its interaction with E-cadherin. Here, we describe that Wnt-induced p120-catenin phosphorylation at Ser268 and Ser269 also enhances its binding to the transcriptional factor Kaiso, preventing Kaiso-mediated inhibition of the β-catenin-Tcf-4 transcriptional complex. Kaiso-mediated repression of this complex ... [more]
