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.

Interaction of the human prostacyclin receptor and the NHERF4 family member intestinal and kidney enriched PDZ protein (IKEPP).

Reid HM, Turner EC, Mulvaney EP, Hyland PB, McLean C, Kinsella BT

Prostacyclin and its I prostanoid receptor, the IP, play central roles in hemostasis and in re-endothelialization in response to vascular injury. Herein, intestinal and kidney enriched PDZ protein (IKEPP) was identified as an interactant of the human (h) IP mediated through binding of PDZ domain 1 (PDZ(D1)) and, to a lesser extent, PDZ(D2) of IKEPP to a carboxyl-terminal Class I ...

Co-localization
Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.
