Structural highlights

Disease

RIT1_HUMAN Noonan syndrome. The disease is caused by mutations affecting the gene represented in this entry.

Function

RIT1_HUMAN Plays a crucial role in coupling NGF stimulation to the activation of both EPHB2 and MAPK14 signaling pathways and in NGF-dependent neuronal differentiation. Involved in ELK1 transactivation through the Ras-MAPK signaling cascade that mediates a wide variety of cellular functions, including cell proliferation, survival, and differentiation.^{[1] [2]}
