Ras GTPase
  #
Binds to GTP/GDP.
- Superfamily consisting of:
- Ras proper
- as well as Rho, Rab, Arf, Ran, RGK, Miro. Rag?
Let’s get this thing straight: it’s the RAS-RAF-MEK(1/2)-ERK(1/2) pathway. In some of these charts, that’s all there is to it in a linear fashion: 
 
 
- 
  
- Downstream, you see Rho Rac, and Cdc42, which proceed into their own cascades.
