Figure 3. ERK, JNK and Src are co-immunoprecipitated with LRP-1 in tumor cells.
Immunoprecipitations of LRP-1-containing complexes (IP: LRP-1-α) were performed by using anti-LRP-1 α-chain (8G1) antibodies and the immunocomplexes were immunoblotted (IB) by using 8G1, anti-LRP-1 β-chain (5A6), anti-ERK-1/2, anti-phospho-ERK-1/2, anti-JNK-1/2/3, anti-phospho-JNK-1/2/3 and anti-Src antibodies. Nonspecific IgGs were used as a negative control of immunoprecipitation.
