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.

Nck beta interacts with tyrosine-phosphorylated disabled 1 and redistributes in Reelin-stimulated neurons.

Pramatarova A, Ochalski PG, Chen K, Gropman A, Myers S, Min KT, Howell BW

The tyrosine phosphorylation sites of the Disabled 1 (Dab1) docking protein are essential for the transmission of the Reelin signal, which regulates neuronal placement. Here we identify Nck beta as a phosphorylation-dependent, Dab1-interacting protein. The SH2 domain of Nck beta but not Nck alpha binds Dab1 phosphorylated on the Reelin-regulated site, Y220, or on Y232. Nck beta is coexpressed with ... [more]
