Product Information

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

R-Ras Antibody detects endogenous levels of total R-Ras protein. This antibody does not cross-react with H-, K-, N- or M-Ras.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy-terminus of human R-Ras. Antibodies are purified by protein A and peptide affinity chromatography.

Background

R-Ras, a member of the small GTPase family, is homologous to H-, K- and N-Ras, but does not activate MAP kinase pathways and is only weakly oncogenic (1). Instead, R-Ras is engaged in integrin activation (2). The effector loop and the carboxy-terminal proline-rich and prenylation sites of R-Ras are critical for integrin activation (3,4). Phosphorylation by EphB2 receptor tyrosine kinase and Src at Tyr66 of R-Ras suppresses integrin activity (5,6).

Alternate Names

Oncogene RRAS; p23; R-Ras; ras family small GTP binding protein R-Ras; RAS related; Ras-related protein R-Ras; related RAS viral (r-ras) oncogene homolog; RRAS
