FunctionSuppresses the insulin receptor and EGFR-transduced MAPK signaling pathway, but does not inhibit MAPK activation by a constitutively active mutant Ras. Probably impairs the formation of GTP-Ras.
Sequence similaritiesBelongs to the sprouty family. Contains 1 SPR (sprouty) domain.
DomainThe Cys-rich domain is responsible for the localization of the protein to the membrane ruffles.
