Original Paper


Dusp22 (dual-specificity phosphatase 22) is considered to regulate various cellular processes through the regulation of protein dephosphorylation. In this study, we prepared a specific antibody against Dusp22, anti-Dusp22, and carried out expression analyses with mouse tissues and cultured cell lines. Western blotting analyses demonstrated a tissue-dependent expression profile of Dusp22 in the adult mouse, and strongly suggested the presence of isoforms with larger molecular masses. In fibroblast NIH3T3 cells, while both endogenous and Myc-tagged Dusp22 was diffusely distributed in the cytoplasm, Myc-Dusp22 was partially colocalized with actin cytoskeleton. From the obtained results, anti-Dusp22 was found to be a useful tool for biochemical and cell biological analyses of Dusp22.
