5.9-S RNA, a new RNA characterized in several mammalian cell lines.
A new species of RNA has been isolated from several different cell lines, both oncornavirus producing and non-producing. This RNA, which we designate 5.9-S RNA is present in the cellular cytoplasmic fraction at very low concentration (approximately 1% of the quantity of 4-S RNA), but it accumulates to much higher levels in two murine oncornaviruses, Moloney murine sarcoma leukemia virus complex and Gross leukemia virus, where it represents as much as 10% of the low-molecular-weight RNA fraction associated with the 70-S RNA genome. The electrophoretic mobility and fingerprint analysis of T1 RNase digest products show that this species of RNA is approximately 160-165-residues long, and can be unequivocally distinguished from all previously described species of RNA in this size range.
