A principal objective of cellular biology is to identify the function of proteins as they interact with their environment. Cellular localization provides context for the function and interactions of proteins. In this study, we seek to identify the localization of three proteins within Saccharomyces cerevisiae through C-terminal green fluorescent protein epitope tagging and subsequent fluorescent microscopy. As 75% of the yeast proteome has been classified, this project seeks to fill the remaining gap in unidentified cellular localization by investigating the proteins fsh3, gid10, and ade13. The analysis of high-resolution localization and comparative phylogenetic data reveals potential cellular environments and protein functions.
