Viral RNAs: Lessons from the Enemy	2009-02-20		.txt	text/plain	3564	172	52	As a result, HIV-1 mutants lacking a functional rev gene are able to express the proteins encoded by fully spliced viral mRNAs, that is, Tat, Nef, and the defective Rev protein itself, but cannot express any of the proteins encoded by incompletely spliced viral mRNAs, including Gag, Pol, and Env. The transcripts encoding these viral structural proteins, however, can be detected in the nucleus of cells infected by Rev-deficient viruses, where they are either degraded or eventually fully spliced and then exported (Cullen, 2003) . MPMV has a simpler genomic organization than HIV-1 and only encodes the three structural proteins Picornaviruses and some flaviviruses Recruits cellular translation factors and ribosomal subunits to viral translation initiation codons in the absence of an mRNA cap Gag, Pol, and Env. Nevertheless, MPMV expresses both a genome-length Gag/ Pol mRNA and a spliced Env mRNA.	./cache/cord-252433-0e9lonq4.txt	./txt/cord-252433-0e9lonq4.txt
