Historical Background

Ras superfamily small GTP (guanosine triphosphate)-binding proteins function as molecular switches, responding to extra- and intracellular stimuli to control the activity of diverse signaling cascades. To date, over 150 different small GTPases have been identified and are classified into six distinct subfamilies – Ras (Rat sarcoma), Rho (Ras homolog gene family), Rab (Ras-related GTP- binding protein), ARF (ADP- ribosylation factor), Ran (Ras-related nuclear protein), and RGK (Rad/Gem/Kir family) – based upon both sequence homology and the regulation of common cellular functions (Colicelli 2004). Rin (Ras-like protein in neurons), along with Rit (Ras-like protein in many tissues) and Drosophila Ric (Ras-related protein which interacted with calmodulin), comprise the Rit subfamily of Ras-related small GTPases (Lee et al. 1996). Rin is expressed exclusively within neurons, including RGCs (retinal ganglion cells)...
