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.

Protein phosphatase 1 binds to phospho-Ser-1394 of the macrophage-stimulating protein receptor.

Santoro MM, Gaudino G, Villa-Moruzzi E

The tyrosine kinase Ron, receptor for MSP (macrophage-stimulating protein), displays several serine residues of unknown functions. Using [(32)P]H(3)PO(4) metabolic labelling, we found that Ron is serine-phosphorylated and dephosphorylated in vitro by PP1 (protein phosphatase 1). PP1 associates with Ron obtained from cells of different origins. The association is stimulated by MSP or serum and is prevented by wortmannin, an inhibitor ... [more]
