MAP2K1IP1

Mitogen-activated protein kinase scaffold protein 1 is a scaffold protein that in humans is encoded by the MAPKSP1 is_associated_with::gene.

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

Interactions
MAP2K1IP1 has been shown to interact with is_associated_with::MAP2K1.
