Phospho-Ros (Tyr2274) Antibody detects endogenous levels of Ros only when phosphorylated at tyrosine 2274. This antibody may cross-react with other unknown proteins.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr2274 of human Ros.
Background
The c-ros proto-oncogene encodes a receptor tyrosine kinase similar to insulin receptor proteins and expressed in specific epithelial cells (1). During mouse development the Ros receptor plays an important role in the differentiation of epididymal epithelium (2). Overexpression or mutation of Ros may lead to oncogenic development. Furthermore, stable transfection with a chimeric receptor containing the Ros transmembrane and cytoplasmic domains leads to transformation of NIH/3T3 fibroblasts (3). A genetic rearrangement that produces a fusion protein containing Ros and FIG (fused in glioblastoma) results in glioblastoma formation (4). The FIG-Ros fusion abnormally activates the SHP-2 phosphatase and PI3K/Akt/mTOR pathways in tumor cells (5). Additional Ros mutations are associated with NSCLC cancer cells indicating that Ros may be a candidate for tumor targeted therapy (6).
