  • Function
    It is a plasma membrane-associated GTP-binding protein with GTPase activity. Might transduce growth inhibitory signals across the cell membrane, exerting its effect through an effector shared with the Ras proteins but in an antagonistic fashion.
  • Tissue specificity
    Ubiquitously present in all tissues examined, with the highest levels in heart, placenta, and skeletal muscle. Moderate levels in lung and liver; low levels in brain, kidney, and pancreas.
  • Involvement in disease
    Ovarian cancer
  • Sequence similarities
    Belongs to the small GTPase superfamily. Ras family.
  • Post-translational
    May be post-translationally modified by both palmitoylation and polyisoprenylation.
  • Cellular localization
    Cell membrane. Inner surface of plasma membrane possibly with attachment requiring acylation of the C-terminal cysteine (By similarity with RAS).

  • Overlay histogram showing A431 cells stained with ab56859 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab56859, 0.1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
  • RRAS2 antibody (ab56859) used in immunohistochemistry at 5ug/ml on formalin fixed and paraffin embedded human dysgerminoma tissue.
  • RRAS2 antibody (ab56859) at 1ug/lane + A-431 cell lysate at 25ug/lane.
