Retroviral-like features in the monomer of the major satellite DNA from the south american rodents of the genus ctenomys

It is well known that uninfected mammalian cells contain DNA sequences which are closely related to retroviral genomic segments. However, these sequences seldom (if ever) have been found associated to highly repetitive (satellite) DNA. RPCS is a 348 bp monomer of a major satellite DNA from the South...

Sumario:It is well known that uninfected mammalian cells contain DNA sequences which are closely related to retroviral genomic segments. However, these sequences seldom (if ever) have been found associated to highly repetitive (satellite) DNA. RPCS is a 348 bp monomer of a major satellite DNA from the South American rodents of the genus Ctenomys. It was found that RPCS contains several elements which are typical of the V) region of retroviral LTRs. These elements are: a) a polypurine tract; b) two enhancer core sequences; c) two NF1 binding sites; d) two C/EBP binding sites; e) two CCAAT-motifs; f) a TATA box, and g) two putative polyadenylation motifs. Furthermore, the relative positions of these elements are as in the U, retroviral regions. © 1993 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
