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 tyrosine phosphatase epsilon inhibits signaling by mitogen-activated protein kinases.

Toledano-Katchalski H, Kraut J, Sines T, Granot-Attas S, Shohat G, Gil-Henn H, Yung Y, Elson A

Mitogen-activated protein kinases (MAPKs) mediate signaling from the cell membrane to the nucleus following their phosphorylation at conserved threonine and tyrosine residues within their activation loops. We show that protein tyrosine phosphatase epsilon (PTP epsilon) inhibits ERK1 and ERK2 kinase activity and reduces their phosphorylation; in agreement, ERK phosphorylation is increased in fibroblasts and in mammary tumor cells from mice ...
