RESUMO
RNase protection-gel retention studies show human host cell-specific ribonucleoprotein complexes with human immunodeficiency virus type 1 Rev-responsive element (RRE) RNA. Nuclear proteins from rodent or murine cells appear to lack the ability to form these complexes. Human-mouse somatic cell hybrids retaining a single human chromosome, either 6 or 12, form the RRE-nuclear-protein complexes. One of the complexes requires the entire RRE RNA, while the other needs RRE RNA stem-loops 1 and 2 only. Two major proteins with molecular masses of 120 and 62 kDa specifically bind to RRE RNA. Rodent cells (CHO) either lack or contain small amounts of these RRE-binding proteins.
