Nucleotide sequences of the retroviral long terminal repeats and their adjacent regions.

The nucleotide sequences of the LTRs and their adjacent regions from 19 type C and one type B retrovirus were compared. Salient features are: (a) The R regions in the genomes of most of the type C retroviruses begin with GC and end with CA. (b) The mammalian type C retroviruses have a polyadenylation signal "AATAAA" in the R region, and most have a "CAT" box and a "TATA" box in the U3 region. (c) The avian type C retroviruses have an AATAAA sequence, and some also have "CAT-like" and "TATA-like" boxes, in the U3 region. (d) As with many transposable elements, the IR regions of the proviruses begin with TG and end with CA, and the DR sequences in the host genomes flanking the proviruses are different from one another. Although SNV is an avian retrovirus, the nucleotide sequences in the R, U5, TBS, and PU region are more similar to the mammalian type C than to the avian type C retroviruses.
