Interaction of Necl-4 with the domain 3 of ErbB3. (a) FLAG-Necl-4 immunoprecipitation assay. HEK293E cells were co-transfected with various combinations of the indicated plasmids and cultured in suspension. FLAG-Necl-4 was immunoprecipitated using the anti-FLAG mAb, and the samples were subjected to Western blotting using the indicated Abs. Asterisks, full-length or mutants of ErbB3. (b) Reciprocal immunoprecipitation assay. HEK293E cells were co-transfected with various combinations of the indicated plasmids and cultured in suspension. ErbB3-GFP and its mutants were immunoprecipitated using the anti-GFP pAb, and the samples were subjected to Western blotting using the indicated Abs. Arrowheads, full-length or mutants of ErbB3. IB, immunoblotting; IP, immunoprecipitation.
