Peterson TA, et al. (1984) A relationship between the yeast cell cycle genes CDC4 and CDC36 and the ets sequence of oncogenic virus E26. Nature 309(5968):556-8
Abstract: We report here significant primary sequence homology among the predicted translational products of three genes: CDC4 , CDC36 and ets. CDC4 and CDC36 are Saccharomyces cerevisiae cell division cycle genes, while ets is a transformation-specific sequence of avian erythroblastosis virus E26. The deduced primary structures of the three gene products were compared by computer to a large data base of known and predicted protein sequences. The search revealed 22.0-25.5% identity over regions of 140-206 codons, respectively between the different pairwise combinations. For these particular sequences, these identity scores fall 3.4-4.0 standard deviations above the empirically-determined mean values of fortuitous similarity. S. cerevisiae calls require CDC36 and CDC4 in order to complete two early events in the cell cycle: execution of start ( CDC36 ) and spindle pole body separation ( CDC4 ). In virus E26, the ets sequence is linked in frame with delta gag and mybE in the tripartite structure 5'-delta gag- mybE -ets-3', comprising the E26 transforming oncogene. The homologies described here suggest that the biochemical functions or regulation of the CDC4 , CDC36 and ets products may be related.
