Proteomics Research

We are interested in the development of technologies which enable the measurement of the dynamic proteome in space and time in a high throughput manner. More specifically, we are interested in looking at the changes in the location, interacting partners and post translational modification of proteins during dynamic cellular processes such as signalling and differentiation.

Research objectives:

What is the impact of post-transcriptional and post-translational processing of RNA and proteins on their interactions and location?

What are the changes in interactions/location upon perturbation, for example during drug treatment?

Do proteins adopt different structures/functions in different locations (moonlighting)?

What role does RNA play in moonlighting (for example RNA-protein interactions and/or localized translation)?

What is the spatial relationship between a protein and its corresponding mRNA?

To enable us to answer the above questions, we have developed a number of technologies and computational tools:

1. Spatial Proteomics

LOPIT - localization of organelle proteomics using isotope tagging
