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.

OS-9 regulates the transit and polyubiquitination of TRPV4 in the endoplasmic reticulum.

Wang Y, Fu X, Gaiser S, Koettgen M, Kramer-Zucker A, Walz G, Wegierski T

Transient receptor potential (TRP) proteins constitute a family of cation-permeable channels that are formed by homo- or heteromeric assembly of four subunits. Despite recent progress in the identification of protein domains required for the formation of tetramers, the mechanisms governing TRP channel assembly, and biogenesis in general, remain largely elusive. In particular, little is known about the involvement of regulatory ... [more]
