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.

TRAPP II complex assembly requires Trs33 or Trs65.

Tokarev AA, Taussig D, Sundaram G, Lipatova Z, Liang Y, Mulholland JW, Segev N

TRAPP is a multi-subunit complex that acts as a Ypt/Rab activator at the Golgi apparatus. TRAPP exists in two forms: TRAPP I is comprised of five essential and conserved subunits and TRAPP II contains two additional essential and conserved subunits, Trs120 and Trs130. Previously, we have shown that Trs65, a nonessential fungi-specific TRAPP subunit, plays a role in TRAPP II ... [more]
