Expression of adenovirus type 5 E4 Orf2 protein during lytic infection.
The human adenovirus type 5 E4 transcription unit has the potential to encode at least seven distinct polypeptides from reading frames accessed by differential splicing of a single primary transcript. Only some of these polypeptides have yet been detected during viral infection of cultured cells. Mutational inactivation of the reading frames whose products have not been described has no apparen...
متن کاملProtein arginine methylation during lytic adenovirus infection.
Arginine methylation of proteins affects major processes in the cell, including transcriptional regulation, mRNA metabolism, signal transduction and protein sorting. Arginine methylation of Ad (adenovirus) E1B 55-kDa-associated protein E1B-AP5 was recently described by us [Kzhyshkowska, Schutt, Liss, Kremmer, Stauber, Wolf and Dobner (2001) Biochem. J. 358, 305-314]. In this first example of pr...
متن کاملAdenovirus type 5 E4 open reading frame 4 protein induces apoptosis in transformed cells.
Adenovirus type 5 E4 open reading frame 4 (E4orf4) protein has been previously shown to counteract transactivation of the junB and c-fos genes by cyclic AMP plus E1A protein and to interact with protein phosphatase 2A (PP2A). Here, we show that the wild-type E4orf4 protein induces apoptosis in the E1A-expressing 293 cells, in NIH 3T3 cells transformed with v-Ras, and in the lung carcinoma cell ...
متن کاملThe E4-6/7 protein functionally compensates for the loss of E1A expression in adenovirus infection.
The E1A gene products are required and sufficient for activation of adenovirus gene expression in cultured cells. The E4-6/7 gene product induces the binding of the cellular transcription factor E2F to the viral E2a promoter region. The induction of E2F binding to the E2a promoter in vitro is directly correlated with transcriptional activation of the E2a promoter in vivo. The E2 region encodes ...
متن کاملLocalization and importance of the adenovirus E4orf4 protein during lytic infection.
The human adenovirus type 5 (Ad5) E4orf4 product has been studied extensively although in most cases as expressed from vectors in the absence of other viral products. Thus, relatively little is known about its role in the context of an adenovirus infection. Although considerable earlier work had indicated that the E4orf4 protein is not essential for replication, a recent study using dl359, an A...
