DNA binding is not sufficient for nuclear localization of regulatory proteins in Saccharomyces cerevisiae.
We showed by immunofluorescence that the procaryotic DNA-binding protein LexA and a chimeric protein that contains the DNA-binding portion of LexA (amino acids 1 to 87) and a large portion (amino acids 74 to 881) of the Saccharomyces cerevisiae positive regulatory GAL4 protein (GAL4 gene product) are not preferentially localized in the nucleus in S. cerevisiae.
