The structure and location of the phosphorylation sites of a number of avian sarcoma virus polyproteins have been examined by protease cleavage analysis. The PRCIIp and PRCII polyproteins, P170gag-fpsand P105gag-fpsyield indistinguishable cleavage fragments from an N-terminal region of 65,000 molecular weight, including thegag/non-gagjunction. This provides strong support for the view that PRCII arose directly from PRCIIp by a genomic deletion. For P909agag-yes, P800gag-yes, and P105gag-fpsthe major tyrosine phosphorylation sites are on C-terminal fragments of 27,000, 26,500, and 36,000 molecular weight, respectively. Further similarities have been shown by partial sequence analysis of the tyrosine phosphorylation sites; the positions of trypsin and staphylococcal V8 protease cleavage sites largely correspond in thesrc, fps, andyesgene products. The homology between thesrcandyesproducts is particularly striking. They yield C-terminal V8-resistant fragments of similar size, containing the major tyrosine phosphorylation sites which are indistinguishable after further cleavage with several proteases. These results suggest structural and functional relatedness between thesrc, fps, andyesgene products despite the lack of hybridization between their DNA sequences.
