Abstract: | We have deduced the sequence of the protein encoded by the chicken c-yes gene from overlapping cDNA clones. The predicted protein, p61c-yes, contains 541 amino acids and has a molecular weight of 60,911 with the amino terminal methionine residue. Chicken p61c-yes differs from Y73 virus p90gag/v-yes in three respects. First, the carboxy-terminal eight amino acids of p61c-yes are replaced by three amino acids in p90gag/v-yes, which are encoded by the avian leukemia virus env gene. This alteration changes the position and context of a tyrosine residue in p61c-yes. Second, nucleotides which are present as 5' non-translated sequence in the p61c-yes mRNA, are translated in the p90gag/v-yes mRNA. Third, there are fourteen dispersed nucleotide differences in Y73 v-yes which result in six amino differences between the body of p90gag/v-yes and p61c-yes. Chicken p61c-yes differs from human p61c-yes at 43 residues, and from chicken pp60c-src at 122 residues. |
