The specific localization and function of Cdc42 isoforms

Cdc42 is a small GTPase protein whose role in polarity is widely studied. However, in vertebrates there exist 2 isoforms arising due to alternative splicing. The function and localization of these have not been studied with respect to cell polarity and cell migration. We therefore perform a mass spec screen to identify interactors of the isoforms to better understand their cellular functions.
