Transdominant negative proto-oncogene

摘要

The present invention provides polynucleotide and polypeptide sequences for a trans-repressing protein of the Fos proto-oncogene family, where the polypeptide is characterized by having a leucine zipper domain and forming a heterodimer with a Jun related protein. This heterodimer is capable of biding to an AP-1 site and suppressing transcriptional transactivation of a promoter containing the AP-1 site.
