This gene encodes a member of the Ras family of small GTPases. These membrane-associated proteins function as signal transducers in multiple processes including cell growth and differentiation, and dysregulation of Ras signaling has been associated with many types of cancer. The encoded protein may play a role in the tumor necrosis factor-alpha and MAP kinase signaling pathways. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011],

Function:
Function:May serve as an important signal transducer for a novel upstream stimuli in controlling cell proliferation. Weakly activates the MAP kinase pathway.,induction:By interleukin-9, but not by IL-2 or IL-4.,similarity:Belongs to the small GTPase superfamily. Ras family.,subunit:Interacts with RGL3.,tissue specificity:Expression highly restricted to the brain and heart.,
