(A) Immunoblot (IB) analysis showing the recruitment of TAK1, MKK7, JNK and TAB1/TAB2 to the phagosome in M2(IL-4) macrophages, while MKK4 is not recruited. Rab7a, a phagosomal marker, was used as a loading control for phagosomes and vimentin was used as a loading control for total cell lysates. The white line in the JNK blot shows other bands were cut out.
