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.

A Novel MAPK phosphatase MKP-7 acts preferentially on JNK/SAPK and p38 alpha and beta MAPKs.

Tanoue T, Yamamoto T, Maeda R, Nishida E

Mitogen-activated protein kinases (MAPKs) are inactivated via dephosphorylation of either the threonine or tyrosine residue or both in the P-loop catalyzed by protein phosphatases which include serine/threonine phosphatases, tyrosine phosphatases, and dual specificity phosphatases. Nine members of the dual specificity phosphatases specific for MAPKs, termed MKPs, have been reported. Each member has its own substrate specificity, tissue distribution, and subcellular ... [more]
