E1A and E1B proteins inhibit inflammation induced by adenovirus.
Replication-defective human adenovirus (Ad) group C transducing vectors, most of which have the E1A, E1B, and E3 genes deleted, are highly inflammatory despite the fact that the parental viruses typically cause subclinical or mild infections. To investigate this paradox, the roles that the E1A, E1B, and E3 genes play in inflammation were tested by using replication-incompetent viruses carrying ...
متن کاملDistinct regulation of p53 and p73 activity by adenovirus E1A, E1B, and E4orf6 proteins.
Multiple adenovirus (Ad) early proteins have been shown to inhibit transcription activation by p53 and thereby to alter its normal biological functioning. Since these Ad proteins affect the activity of p53 via different mechanisms, we examined whether this inhibition is target gene specific. In addition, we analyzed whether the same Ad early proteins have a comparable effect on transcription ac...
متن کاملRIP and FADD: two "death domain"-containing proteins can induce apoptosis by convergent, but dissociable, pathways.
With use of the yeast two-hybrid system, the proteins RIP and FADD/MORT1 have been shown to interact with the "death domain" of the Fas receptor. Both of these proteins induce apoptosis in mammalian cells. Using receptor fusion constructs, we provide evidence that the self-association of the death domain of RIP by itself is sufficient to elicit apoptosis. However, both the death domain and the ...
متن کاملA role for E1B-AP5 in ATR signaling pathways during adenovirus infection.
E1B-55K-associated protein 5 (E1B-AP5) is a cellular, heterogeneous nuclear ribonucleoprotein that is targeted by adenovirus (Ad) E1B-55K during infection. The function of E1B-AP5 during infection, however, remains largely unknown. Given the role of E1B-55K targets in the DNA damage response, we examined whether E1B-AP5 function was integral to these pathways. Here, we show a novel role for E1B...
متن کاملInactivation of p53 but not p73 by adenovirus type 5 E1B 55-kilodalton and E4 34-kilodalton oncoproteins.
The adenovirus E1B 55-kDa and E4 34-kDa oncoproteins bind and inactivate the p53 tumor suppressor gene product, resulting in cell transformation. A recently discovered cellular protein, p73, shows extensive similarities to p53 in structure and function. Here we show that the simultaneous transient expression of E1B 55-kDa and E4 34-kDa proteins is sufficient to drastically shorten the intracell...
