title: Evidence against the existence of the purported Saccharomyces cerevisiae PKC2 gene.
abstract: BACKGROUND
  The existence of a Saccharomyces cerevisiae gene encoding a novel isoform of protein kinase C was reported recently in this journal.
  
  
  RESULTS
  We demonstrate here that, firstly, the purported PKC2 gene does not reside at the chromosomal location to which it was assigned; secondly, it does not exist as a contiguous sequence in the S. cerevisiae genome; thirdly, some of its reported sequences do exist within other yeast genes; and fourthly, some of its reported sequences, encoding regions of the predicted protein related to protein kinase C, do not exist in any context in the yeast genome.
  
  
  CONCLUSIONS
  We conclude from these studies that the PKC2 gene is a composite construction of unrelated yeast and non-yeast sequences.
