H-Ras Polyclonal Antibody, Invitrogen™

Descripción

This antibody is predicted to react with mouse and rat based on sequence homology.

Monomeric G protein Ras functions as a molecular switch linking receptor and nonreceptor tyrosine kinase activation to a number of downstream signaling pathways leading to distinct cytoplasmic or nuclear events. Each mammalian cell contains three Ras proto-oncogene coding for closely related Ras proteins: H-, K-, N-Ras. Oncogenic mutations in Ras genes are present in ∽30% of all human cancers. Constitutive activation of Ras due to mutations or overexpression stimulates proliferation and inhibition of apoptosis. K-Ras mutations are common in pancreatic, colorectal and nonsmall-cell lung carcinomas; H-Ras mutations are common in bladder, kidney and thyroid carcinomas; N-Ras mutations are found in melanoma, hematological malignancies and hepatocellular carcinaoma.
