Transmembrane serine protease overexpressed in ovarian carcinoma and uses thereof
View Patent ↗The present invention provides a transmembrane serine protease TADG-12 protein, splice variants of the TADG-12 protein and DNA fragments encoding such proteins. Also provided are vectors and host cells capable of expressing the DNAs. The present invention further provides various methods of early detection and therapies of associated ovarian and other malignancies by utilizing the DNAs and/or proteins disclosed herein.
1. An isolated DNA fragment encoding a Tumor Associated Differentially-Expressed Gene-12 (TADG-12) said DNA is selected from the group consisting of:
(a) an isolated DNA fragment with the sequence shown in SEQ ID NO:1 and encoding a TADG-12 protein with the amino acid sequence shown in SEQ ID NO:2;
(b) an isolated DNA fragment with the sequence shown in SEQ ID NO:3 that differs from the isolated DNA fragment of (a) above due to inclusion of an intron sequence and a new stop codon and encoding a TAGD-12 protein with the amino acid sequence shown in SEQ ID NO:4; and
(c) an isolated DNA fragment differing from the isolated DNA fragments of (a) and (b) above in codon sequence due to the degeneracy of the genetic code.
2. A vector comprising the DNA fragment of claim 1 and regulatory elements necessary for expressing said DNA in a cell.
3. An isolated host cell transfected with the vector of claim 2 , said vector expressing a TADG-12 protein.
4. An isolated host cell of claim 3 , wherein said cell is a mammalian cell.
