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.

CD46 is phosphorylated at tyrosine 354 upon infection of epithelial cells by Neisseria gonorrhoeae.

Lee SW, Bonnah RA, Higashi DL, Atkinson JP, Milgram SL, So M

The Neisseria type IV pilus promotes bacterial adhesion to host cells. The pilus binds CD46, a complement-regulatory glycoprotein present on nucleated human cells (Kaellstroem et al., 1997). CD46 mutants with truncated cytoplasmic tails fail to support bacterial adhesion (Kaellstroem et al., 2001), suggesting that this region of the molecule also plays an important role in infection. Here, we report that ... [more]
