WebJun 2, 2016 · The life cycle of endogenous retroviruses (ERVs), also called long terminal repeat (LTR) retrotransposons, ... Most LINE elements are truncated at the 5′ end, thus lacking the 5′ UTR promoter and TSS. (B) Full-length ERVs have 5′ and 3′ LTRs, and an “internal” region that includes a primer-binding site ... 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.
