Function

edit

The protein encoded by this gene was identified as an interacting protein that binds specifically to MAP kinase kinase MAP2K1/MEK1 and to MAP kinase MAPK2/ERK1. This protein enhances the activation of MAPK2, and thus is thought to function as an adaptor to enhance the efficiency of the MAP kinase cascade.[7]

Interactions

edit

MAP2K1IP1 has been shown to interact with MAP2K1.[5][8]
