Systematic Discovery of Protein Function
One of the hallmarks of eukaryotic cells is the presence of membrane-enclosed organelles that create optimized environments best suited for promoting the various chemical reactions required to sustain life. Although nearly 30 years have passed since the publication of the Saccharomyces cerevisiae genome sequence, over 25% of the proteins still do not have a known biochemical function.
Most of these proteins are conserved all the way to humans and some have been implicated in diseases. One of the great challenges of the post-genomic era is, therefore, to use novel methodologies to fill in these gaps in our knowledge, to uncover the functions of these unstudied proteins.
Our lab is dedicated to uncovering novel functions for yeast organellar proteins. We do this by employing a wide variety of high throughput screening techniques complemented by dedicated cell biological, genetic and biochemical follow ups.

Ofir's Research
Trace metals homeostasis in mitochondria
Ofir is fascinated by the role of trace metals in the cell as a whole and is focusing on their flux in mitochondria. Trace metals such as zinc and copper are found in extremely low concentrations in mitochondria but are essential for all mitochondrial functions. Ofir hopes to unravel how such metals are regulated and transported in and out of mitochondria.
Sarah's Research
Development of Multi-CLEM in
mammalian cells
Sarah is developing a high-throughput screening approach (multi-CLEM) for electron microscopy in mammalian cells. The combination of fluorescence microscopy for barcoding of tens or hundreds of differently manipulated cells and electron microscopy will allow quantitative imaging at the ultrastructure level.

Advancing Protein Localization in Yeast:
A Unique Tagging Strategy.
Din is focused on advancing the understanding of protein localization within yeast cells. By developing a novel yeast library, a collection of yeast strains in which each yeast proteins is tagged with a unique approach that overcomes some of the disadvantages of big bulky tags, he is offering a more refined approach to tracking protein dynamics.
