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.

Zinc finger protein Wiz links G9a/GLP histone methyltransferases to the co-repressor molecule CtBP.

Ueda J, Tachibana M, Ikura T, Shinkai Y

G9a is a SET-domain mammalian histone methyltransferase responsible for mono- and dimethylation of lysine 9 in histone H3 (H3K9) at euchromatic regions. Recently we reported that G9a forms a stoichiometric heteromeric complex with another SET-domain-containing molecule, GLP/Eu-HMTase1. Although G9a and GLP can independently methylate H3K9 in vitro, G9a/GLP heteromeric formation seems to be essential for their function as a euchromatic ... [more]
