Research interests

My lab is interested in endosomal sorting machineries and the cellular processes in which they are involved. Many eukaryotic cell surface proteins (such as growth factor receptors) are selectively removed from the plasma membrane by endocytosis and then either sorted into late endosomes/multivesicular bodies (MVBs) for degradation or recycled back to the plasma membrane. The fate of endocytic cargoes has implications for cell programming and can influence cellular processes such as the cell cycle, apoptosis, migration and cell fate determination. Defects in endocytic sorting have been linked to a variety of human diseases such as cancer and neurodegeneration.

Much of our research is concerned with the function of the ESCRT machinery which is primarily involved in the formation of MVBs and the selective destruction of membrane proteins. At least three endosomal sorting complexes required for transport (ESCRT-I, II and III) and various membrane lipids (PtdIns(3)P, PtdIns(3,5)P2 and LBPA) have been implicated in the biogenesis of MVBs. We found that one of the ESCRT-III components, charged multivesicular body protein 3 (CHMP3/Vps24) binds selectively to the phosphatidylinositol lipid PtdIns(3,5)P2 in vitro (Whitley et al 2003) and have an interest in the cellular function of this lipid (Dukes et al 2006, Whitley et al 2009). Recent work in the lab has focused on investigating the links between defects in endosomal sorting and cell polarity in mammalian cells. We have demonstrated that in mammalian epithelial cells that depletion of ESCRT proteins results in loss of epithelial sheet organisation and a multi-layered cell phenotype (Dukes et al 2011). As loss of cell polarity is one of the hallmarks of epithelial cancers we are currently investigating potential mechanisms behind the loss of polarity in ESCRT ‘mutant’ cells and other tumour suppressive properties of endosomal sorting proteins in mammalian epithelial cells.
