WebLTR retrotransposons contain two long-terminal repeats (LTRs), as shown in 1, at their ends, typically 250–Figure 600 bp in length, flanking a 5–7 kb long internal protein-coding domain.16 Between the two LTRs are two open reading frames (ORFs): gag and pol. The gag ORF encodes the structural pro- WebJun 1, 1998 · However, the use of HIV-1 vectors raises concerns about their safety. Here we describe a self-inactivating HIV-1 vector with a 400-nucleotide deletion in the 3′ long terminal repeat (LTR). The deletion, which includes the TATA box, abolished the LTR promoter activity but did not affect vector titers or transgene expression in vitro.
