The Grb2 splice variant, Grb3-3, is a negative regulator of RAS activation
The Grb2 splice variant Grb3-3 results in decreased activation of the Ras-MAPK pathway due competition with Grb2 for SOS binding, with reduced Grb3-3 levels observed in tumour tissue suggestive of a mechanism for enhancing Ras pathway activity.
