Figure 5. DOK3 associates with Grb2 and SOS1 and promotes SOS1 degradation in response to LPS.

Figure 5

BMM were stimulated with 1 µg/ml LPS for indicated time and cell lysates were immunoprecipitated with (A) anti-DOK3 antibody or (B) anti-Grb2 antibody followed by immunoblotting for DOK3, Grb2, and SOS1. As a control, isotype matched antibody was used for immunoprecipitation (Con Ig). Protein levels were quantified using Image J. (C) Wild type and DOK3−/− BMM were stimulated with 1 µg/ml LPS for indicated time and immunoblotted for SOS1 and GAPDH. (D) BMM were treated with NH4CL or PBS (control) and were stimulated with 1 µg/ml LPS and immunoblotted for SOS1 and GAPDH. Data are representative of three independent experiments.
