We have found that a major interaction also exists between 尾-arrestin1 and the catalytic or kinase domain (SH1) of c-SRC. We therefore hypothesized that a catalytically inactive mutant of the isolated catalytic subunit, SH1(kinase dead) (SH1(KD)), would specifically block those cellular ...
Western blotting was used to detect the expression of JNK and p-JNK in the cells, and co-immunoprecipitation (Co-IP) assay was employed to investigate the interaction between β-arrestin1 and Src. RESULTS K562-β1 cells showed significantly greater but ...
