The invention discloses a newly discovered Flt3 phosphorylation site, tyrosine 969 (Tyr969) in the intracellular domain, and provides reagents, including polyclonal and monoclonal antibodies, that selectively bind to Flt3 when phosphorylated at this site. Also provided are assays utilizing this reagent, including methods for determining the phosphorylation of Flt3 in a biological sample, selecting a patient suitable for Flt3 inhibitor therapy, profiling Flt3 activation in a test tissue, and identifying a compound that modulates phosphorylation of Flt3 in a test tissue, by using a detectable reagent, such as the disclosed antibody, that binds to Flt3 only when phosphorylated at Tyr969. The sample or test tissue may be taken from a subject suspected of having cancer, such as acute myelogenous leukemia (AML).

摘要:
The invention provides the identification of the presence of polypeptides with ROS kinase activity in mammalian lung cancer. In some embodiments, the polypeptide with ROS kinase activity is the result of a fusion between a ROS-encoding polynucleotide and a polynucleotide encoding a second (non-ROS) polypeptide. Three different fusion partners of ROS are described, namely proteins encoded by the FIG gene, the SLC34A2 gene, and the CD74 gene. The invention enables new methods for determining the presence of a polypeptide with ROS kinase activity in a biological sample, methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer (e.g., an lung cancer).
摘要:
In accordance with the invention, a novel gene translocation, (5q32, 6q22), in human non-small cell lung carcinoma (NSCLC) that results in a fusion proteins combining part of CD74 with Proto-oncogene Tyrosine Protein Kinase ROS Precursor (ROS) kinase has now been identified. The CD74-ROS fusion protein is anticipated to drive the proliferation and survival of a subgroup of NSCLC tumors. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ROS kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides. The disclosed identification of the new fusion protein enables new methods for determining the presence of these mutant ROS kinase polypeptides in a biological sample, methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer characterized by the mutant polynucleotides or polypeptides, which are also provided by the invention.
