PR/SET-DOMAIN CONTAINING NUCLEIC ACIDS, POLYPEPTIDES, ANTIBODIES AND METHODS OF USE

摘要

The present invention provides an isolated nucleic acid molecule encoding a PFM/SET polypeptide. Also provided is an isolated nucleic acid molecule encoding a functional fragment of a PFM/SET polypeptide that contains a SET domain of a PFM/SET polypeptide of the invention. Further provided by the invention are PFM/SET polypeptides, and functional fragments thereof that contain a SET domain of a PFM/SET polypeptide. The invention also provides PFM/SET antibodies, PFM/SET modulatory compounds, and related methods. The molecules of the invention can be used in methods of screening for a compound that modulates PFM/SET polypeptide histone methyltransferase activity and to modulate cell proliferation to prevent or treat proliferative disorders, including cancer. Additionally, the molecules and methods of the invention can be used to diagnose and prognose proliferative disorders.
