Cellular adhesion plays important roles in a variety of biological processes. The ADAM family contains disintegrin-like and metalloproteinase-like domains which potentially have cell adhesion and protease activities. Recent studies suggest that the interaction between 14-3-3ζ and ADAM22cyt can regulate cell adhesion and spreading, therefore it has a potential role in neural development and function. 14-3-3 family has seven highly conserved members that regulate various cellular functions. Using yeast two-hybrid method, we identified that ADAM22cyt bound some other 14-3-3 family members. The interaction was further confirmed by in vitro protein pull-down assay and co-immunoprecipitation. We also found that the overexpression of exogenous ADAM22 in HEK293 cells could significantly enhance cell adhesion and spreading, compared with the truncated ADAM22 lack of 14-3-3 binding motifs. These results strongly demonstrated a functional role for ADAM22/14-3-3 in cell adhesion and spreading.
