Efficient polyadenylation within the human immunodeficiency virus type 1 long terminal repeat requires flanking U3-specific sequences
Year: 1991
Type: article
Abstract: During transcription of the human immunodeficiency virus type 1 provirus, polyadenylation signals present in the 5' long terminal repeat (LTR) are disregarded while the identical polyadenylation signals present in the 3' LTR are utilized efficiently. As both transcribed LTR sequences contain all signals known to be required for efficient polyadenylation, the basis for this differential utilization has been unclear. Here, we describe experiments that suggest that transcribed sequences present within the human immunodeficiency virus type 1 LTR U3 region act in cis to enhance polyadenylation within the 3' LTR.
