c-mip interacts with PAG and Fyn in HRS cell lines. (A) Western blot detection of c-mip protein in lysates from HRS and Jurkat cell lines. Human embryonic kidney (HEK) cells were transfected with a c-mip expression plasmid and were used as positive controls. Immunoprecipitation of endogenous Fyn (B) and PAG/Cbp (C) from HRS cell lines cotransfected with the c-mip expression plasmid or empty vector (Ev).
