The nuclear import of the small GTPase Rac1 is mediated by the direct interaction with karyopherin alpha2.

Sandrock K, Bielek H, Schradi K, Schmidt G, Klugbauer N

The small GTPase Rac1 is involved in multiple cytosolic functions but recent data point out that Rac1 also translocates to the nucleus to regulate signalling pathways that control gene expression and progression through the cell cycle. Here, we identify the nuclear import receptor karyopherin alpha2 (KPNA2) as a direct interaction partner of Rac1. The C-terminal polybasic region of Rac1 contains ... [more]

Affinity Capture-MS

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 is identified by mass spectrometric methods.

Affinity Capture-Western
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.
