  • attached to the membrane by a lipid anchor, at internal side of plasma membrane
  • associated with both the outer membrane and inner mitochondrial compartments
  • membrane protein that shuttles between the golgi apparatus and the plasma membrane, shutlling regulated through palmitoylation and depalmitoylation (Rocks 2005)
  • basic FUNCTION
  • possessing intrinsic GTPase activity
  • has an immune regulatory function and its absence or gain-of-function affects primarily hematopoietic cells
  • having a farnesylation independent function and within the inner mitochondrial compartment being an essential component of the retrograde signaling system between the mitochondria and nucleus
  • tumor type–specific mutation spectrum of Ras genesis dictated by their regulation of expression and that the altered Ras proteins that can be palmitoylated act as particularly potent oncoproteins

  • CHMP6 and VPS4A bound to NRAS but not KRAS
  • DDX43 may promote NRAS protein expression by unwinding and stabilizing NRAS mRNA, therefore enhancing its translation
