There are now many methods available for studying protein interactions between DNA methltransferases (DNMTs) and their binding partners. Here we describe a step-by-step procedure to identify whether proteins of interest interact with DNMTs by co-immunoprecipitation (co-IP) assay in transiently transfected cells. Though one mammalian cell is described, investigators can use the same method with other cell lines or primary cells for in vivo protein interaction studies.
