专利号:US-7052692-B1 优先权日:1997-09-02 标题:Role of tyrosine phosphorylation of a cellular protein in adeno-associated virus 2-mediated transgene expression 发明人:SRIVASTAVA ARUN; QING KEYUN; WANG XU-SHAN; PONNAZHAGAN SELVARANGAN; BAJPAI ANIL 权利人:ADVANCED RES & TECH INST 摘要:The present invention identifies a protein, designated the D-sequence-binding protein (D-BP), is phosphorylated at tyrosine residues and blocks AAV-mediated transgene expression in infected cells by inhibiting the leading strand viral DNA synthesis. More particularly, the present invention demonstrates that D-BP is phosphorylated by EGF-R protein tyrosine kinase. Methods of increasing transcription and promoting replication of transgenes exploiting this information are disclosed herein.
