Bait protein expressed as a DNA binding domain (DBD) fusion and prey expressed as a transcriptional activation domain (TAD) fusion and interaction measured by reporter gene activation.


SmgGDS displays differential binding and exchange activity towards different Ras isoforms.

Vikis HG, Stewart S, Guan KL

Ras family GTPases play central roles in a wide variety of biological responses, including cell proliferation, differentiation, and oncogenic transformation. We searched for novel guanine nucleotide exchange factors of HRas and isolated small G-protein dissociation stimulator (smgGDS), a guanine nucleotide exchange factor known to act on numerous Ras and Rho family GTPases. SmgGDS specifically interacts with both dominant negative and ... [more]

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.
