Figure 3. Specificities of Gab1 and Gab2 siRNAs.
(A) Alignment of human Gab1 and Gab2 siRNA targeting nucleotide sequences with the corresponding sequences in mouse Gab1 and Gab2. (B, C) COS-7 cells were co-transfected with pGab1siRNA, pGab2siRNA or empty vector (1.8 μg) and FLAG-tagged human Gab1 (hGab1), human Gab2 (hGab2), mouse Gab1 (mGab1) or mouse Gab2 (mGab2; 0.2 μg) as indicated. Cell lysates (30 μg) were subjected to immunoblot analyses with antibodies to the FLAG-tag and β-actin after 48 h transfection.
