Abstract
Four putative hairpin structures (hairpins A to D) are involved in the specific encapsidation of Moloney murine leukemia virus (M-MuLV) RNA into M- MuLV virus particles. The C and D elements, encompassing M-MuLV viral nucleotides 310 to 374, facilitate encapsidation of heterologous RNA into virions. Thus, these two elements appear to act as a core RNA encapsidation signal. The loop sequences of the putative C and D hairpins are identical (GACG). However, when GACG loops were introduced into RNAs on heterologous stem sequences, they increased encapsidation levels only three- to fourfold. These results suggest that C and D stem-and-loop sequences contribute to the M-MuLV cis-acting site for encapsidation.
