NotesThis vector was given by U. GŸldener and J. H. Hegemann from Heinrich-Heine-UniversitŠt in Germany. If a work is published using this vector, proper citation is required! The green fluorescent protein (GFP) of the jellyfish Aequorea victoria has proven to be an extremely useful tool as a marker for gene expression and as a tag to study protein localization. Previously we developed the vectors pGFP-N-FUS and pGFP-C-FUS which allow the N-terminal or C-terminal in-frame fusion of the gfp wildtype gene to the gene of interest and subsequent determination of the subcellular location of the fusion protein. Based on this first set of vectors a new series of GFP vectors equipped with the yEGFP version constructed by Cormack and coworkers . In this yEGFP version all codons of the original gfp gene were exchanged by optimal codons for Candida albicans. In addition 2 amino acid changes were incorporated near the chromophore that had been shown to increase GFP fluorescence . The yEGFP3 not only proved to exhibit stronger fluorescence, but the maturation from the non-fluorescent preform to the mature fluorescence form occurs much faster. The gene encoding the yEGFP3 protein was inserted in the polylinker of the CEN/ARS vectors p413MET25 (HIS3 marker) and p416MET25 (URA3 marker) . Eight (nine in the case of the N-FUS vectors) different restriction sites can be used to insert the gene of interest in frame N-terminal (plasmids pUG23 and pUG35) or C-terminal (plasmids pUG34 and pUG36) to the yEGFP3 encoding open reading frame. The expression level of the fusion protein can be regulated by adding methionine to the media. http://mips.gsf.de/proj/yeast/info/tools/hegemann/gfp.html
