The Ras family (K-Ras, H-Ras, and N-Ras) includes 21 kDa guanine-nucleotide binding proteins that cycle between active (GTP-bound) and inactive (GDP-bound) forms. Receptor tyrosine kinases and G-protein-coupled receptors activate Ras, which then stimulates the Raf-MEK-MAP kinase pathway. Both GTPase-activating proteins (GAPs), such as p120 Ras-GAP, and guanine-nucleotide exchange factors (GEFs) regulate the activity of Ras proteins in many cell signaling pathways. Mutations in Ras are found in several cancers, and the most common oncogenic mutation is Gly12 to Asp (G12D), which prevents Ras inactivation.

Western blot of mouse brain (lane 1), human A431 (lane 2), Jurkat (lane 3), and SYF fibroblast lysates. The blot was probed with mouse monoclonal anti-RasGAP antibody at 1:1000.

Immunocytochemical labeling of RasGap in aldehyde-fixed and NP-40-permeabilized A431 cells. The cells were labeled with mouse monoclonal RasGap (RM3351) antibody, then the antibody was detected using appropriate secondary antibody conjugated to DyLight® 594. The cells were counterstained with Sytox green to label nuclei.

Clone (M335) was generated from a recombinant sequence in the central region of human RasGAP. This sequence has high homology to mouse and rat RasGAP.
