SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	may play important roles in the regulation of signaling pathways and cellular processes distinct from those controlled by Ras
	implicated in a novel pathway of neuronal development and regeneration by coupling specific trophic factor signals to sustained activation of the B-Raf/ERK and p38 MAP kinase cascades
	plays a key role in human neuronal development and regeneration through activating both known and as yet undefined signaling pathways
	differentially regulates axonal and dendritic growth
	may be involved in the signaling pathway for Goalpha-mediated neuronal differentiation
	role for RIT1 in injury-induced neurogenesis, functioning as a selective survival mechanism for immature hippocampal neurons within the subgranular zone of the dentate gyrus following traumatic brain injury (TBI)
	critical role for the RIT1-MAPK14 signaling cascade in promoting hippocampal neuron survival following oxidative stress
