Translation of type C viral RNAs in Xenopus laevis oocytes: evidence that the 120,000-molecular-weight polyprotein expressed in Abelson leukemia virus-transformed cells is virus coded.

ABSTRACT

The genomic RNA of Abelson leukemia virus (AbLV) has been purified and translated in Xenopus laevis oocytes. The primary AbLV-specific protein synthesized is a polyprotein corresponding in molecular weight and immunological properties to a previously described p15 and p12 containing 110,000- to 130,000-molecular-weight polyprotein expressed in AbLV-transformed cells. In contrast, translation of woolly monkey sarcoma virus genomic RNA resulted in symthesis of a 55,000-molecular-weight polyprotein consisting of woolly helper virus p30, p15, and p12. These findings demonstrate the value of the X. laevis oocyte in vitro system for studies of translational products of replication-defective transforming viruses and establish the virus-coded nature of the nonstructural component of the 110,000- to 130,000-molecular-weight polyprotein expressed in AbLV-transformed cells.
