The WD40 domain containing proteins are present in the lower organisms (Monera) to higher complex metazoans with involvement in diverse cellular processes. The WD40 repeats fold into β propeller structure due to which the proteins harbouring WD40 domains function as scaffold by offering platform for interactions, bring together diverse cellular proteins to form a single complex for mediating downstream effects. Multiple functions of WD40 domain containing proteins in lower eukaryote as in Fungi have been reported with involvement in vegetative and reproductive growth, virulence etc. In this article insilico analysis of the WDR proteins in the budding yeast Saccharomyces cerevisiae was performed. By WDSP software 83 proteins in S. cerevisiae were identified with at least one WD40 motif. WD40 proteins with 6 or more WD40 motifs were considered for further studies. The WD40 proteins in yeast …
