title: Functional analysis of the yeast genome: use of two-dimensional gel electrophoresis to detect genes in randomly cloned DNA sequences.
abstract: Genes are overexpressed when present in yeast cells on multicopy plasmids. Taking advantage of the protein amplification which results from this overexpression, a method has been developed for large scale detection of yeast genes on randomly cloned DNA sequences. It is based on the analysis, by two-dimensional gel electrophoresis, of the proteins from yeast cells transformed with a yeast genomic DNA library constructed in a multicopy vector. We demonstrate here the applicability of this method for exploring the yeast genome. In addition, we report results which suggest that this method may also be useful for detecting regulatory genes.
