Differential nuclear localization of the major adenovirus type 2 E1a proteins.
The localization in infected and transformed cells of the two major adenovirus type 2 E1a proteins, of 289 and 243 amino acid residues, was studied with antisera raised against synthetic peptides or a TrpE-E1a fusion protein. Both E1a proteins were detected only in the nucleus of infected cells as determined by immunofluorescence analysis of cells infected with wild-type virus or with the mutan...
متن کاملEpigenetic reprogramming by adenovirus e1a.
Adenovirus e1a induces quiescent human cells to replicate. We found that e1a causes global relocalization of the RB (retinoblastoma) proteins (RB, p130, and p107) and p300/CBP histone acetyltransferases on promoters, the effect of which is to restrict the acetylation of histone 3 lysine-18 (H3K18ac) to a limited set of genes, thereby stimulating cell cycling and inhibiting antiviral responses a...
متن کاملNuclear-localization-signal-dependent and nuclear-export-signal-dependent mechanisms determine the localization of 5-lipoxygenase.
5-Lipoxygenase (5-LO) metabolizes arachidonic acid to leukotriene A4, a key intermediate in leukotriene biosynthesis. To explore the molecular mechanisms of its cell-specific localization, a fusion protein between green fluorescent protein (GFP) and human 5-LO (GFP-5LO) was expressed in various cells. GFP-5LO was localized in the cytosol in HL-60 cells and in both the nucleus and the cytosol in...
متن کاملFunctional interactions between YY1 and adenovirus E1A.
YY1 is a C2H2-type zinc finger transcription factor that is a member of the human GLl-Kruppel family of proteins. YY1 represses transcription when bound upstream of transcription initiation sites. The repression can be relieved by adenovirus E1A and activation of target genes occurs. We have mapped the repression domain of YY1 to the C-terminal region, overlapping its DNA binding domain. We hav...
متن کاملRegulation of the human proliferating cell nuclear antigen promoter by the adenovirus E1A-associated protein p107.
The adenovirus E1A 243R oncoprotein is capable of transactivating the expression of the human proliferating cell nuclear antigen (PCNA) promoter. Mutational analysis of the E1A 243R protein suggested that both its p300/CBP- and p107-binding regions are required for optimal induction of the PCNA promoter (C. Kannabiran, G. F. Morris, C. Labrie, and M. B. Mathews, J. Virol. 67:425-437, 1993). We ...
