Analysis of Bves function through identification of interacting proteins.
Smith, Travis Kirk
The work contained in this document describes the generation of new immunoreagents for Bves study, and our identification of a Bves-interacting protein. After generating new monoclonal antibodies to the Bves protein, I here describe the characterization of Bves expression throughout mouse embryogenesis, clearly demonstrating that Bves is widely expressed in many tissue types throughout gestation. I also describe the isolation of Geft as a directly interacting protein for Bves, and biochemically confirm and characterize the interaction between these two proteins. I then demonstrate a role for Bves in control of cellular motility via modulation of the Rac1/Cdc42 GTPases, likely through the Geft interaction. These findings represent both the first identification of a Bves-interacting protein and the first placement of Bves into a molecular pathway within the cell. The data presented here will undoubtedly serve as a departure point for many future investigations into the Bves protein, and represent seminal findings in the study of Bves function.
