title: The interaction between ADAM22 and 14-3-3beta.
abstract: ADAM family consists of a number of transmembrane proteins that contain a disintegrin and metalloprotease domain. ADAMs are involved in a highly diverse set of biological processes, including fertilization, neurogenesis, myogenesis and inflammatory response. The ADAM proteins have both cell adhesion and protease activities. Adam22 is highly expressed in human brain. The adam22-/- mice presented severe ataxia and died before weaning, but the function of ADAM22 is still unknown. 14-3-3 beta interacting with ADAM22 was detected by using yeast two-hybrid assay. The specificity of interaction between ADAM22 and 14-3-3beta was proved by in vitro binding assay and immunoprecipitation. The major 14-3-3beta binding site was located in the last 28 amino acid residues of ADAM22 cytoplasmic tail. Protein 14-3-3beta is abundant and plays an important role in mediating cell diffusion, migration and cell cycle control. The interaction of ADAM22 and 14-3-3beta suggests that the ADAM22 may play a crucial role in neural function and development.
