Abstract: A novel gene designated as FRAG1 and its encoded protein is disclosed. A fusion protein called FGFR2-ROS, which is formed by chromosomal rearrangement of rat FRAG1 with FGFR2, is also disclosed. Methods of producing FRAG1 protein, related fusion proteins, and antibodies against FRAG1 are disclosed, as are related pharmaceuticals and methods of using such nucleic acids, polypeptides, and antibodies are also disclosed.

Abstract: The oncogene of the present invention, isolated by expression cloning from a human ovarian cancer is a mutant of TC21. The present invention teaches that ras-related genes not thought to have transforming potential can contribute importantly to cancers which have been refractory to oncogene detection. The present invention teaches that another ras relative gene, R-ras, which was previously reported to lack transforming potential, has transforming capacity as well. Thus, these and other genes similarly related to prototype and activated by analogous mechanisms may be important in the diagnosis and prognosis of certain cancers, as well as be critical in the design of rational approaches to therapy of cancers in which they play a role.

Abstract: A highly efficient genetic cloning system is disclosed which is particularly useful for cloning cDNA copies of eukaryotic mRNAs and can direct the orientation of inserts in .lambda.-plasmid composite vectors with large cloning capacities. Cleavage of such vector DNA, by the restriction enzyme SfiI, for example, creates two different non-symmetrical 3' extensions at the ends of vector DNA. Using a linker-primer and an adaptor, cDNA is prepared to have two different sticky ends which can be ligated to those of the vector. When the cDNA fragments and the vector DNAs are mixed, both the molecules can assemble without self-circularization due to base-pairing specificity. This system provides (1) high cloning efficiency (10.sup.7 -10.sup.8 clones/.mu.g poly(A).sup.

Abstract: A method for the identification of related polypeptides, using an function-based selection criterion, is disclosed. A novel human phosphatase, and nucleotide sequences coding therefor, identified by the aforementioned method and designated VHR, is also disclosed.
