General description

GTPase KRas (c-k-ras; K-ras) is a membrane-bound G protein belonging to the family of Ras GTPases. They are activated by the binding of GTP in response to signals from various receptors including the epidermal growth factor receptor (EGFR). Ras GTPases are regulated by guanine nucleotide exchange factors (GEF) and GTPase activating proteins (GAP) and lie upstream of the MAP kinase pathway which controls a range of cellular processes including proliferation and differentiation. Previous studies have suggested that KRas plays an important role in embryonic development, and it may also contribute to the pathogenesis of colorectal cancer via an EGFR-mediated pathway.

Immunogen

Recombinant protein corresponding to rat c-K-Ras.

This Anti-c-K-Ras Antibody, clone 234-4.2 is validated for use in Western Blotting, IHC for the detection of c-K-Ras.
Western Blot Analysis: A representative lot detected c-K-Ras in A431 cell lysate.

Western Blot Analysis: A representative lot from an independent laboratory detected c-K-Ras in primary human
lymphoid leukemia cell lysates, and in normal and HA-dynamin K44A mutant HeLa cell lysates (Omerovic, J., et al. (2008). Oncogene. 27(19):2754-2762.).

Immunohistochemistry Analysis: A representative lot from an independent laboratory detected c-K-Ras in non-small cell lung cancer cells (Volm, M., et al. (2002). Clin Cancer Res. 8(6):1843-1848.).
