Understanding asymmetric cell divisions at the onset of life

Application deadline: 21 January 2019

Start of PhD: 1 October 2019 (3.5 years)

To generate a complex organism from a single-cell embryo, cells divide asymmetrically acquiring structural and functional differences. This polarisation is essential for tissue and organ development and depends on the localisation of conserved effectors, notably PAR proteins, to discrete cell membrane domains. A wide range of developmental problems are associated with impaired PAR function (e.g. cardiovascular, neurodegenerative diseases and cancer). Consequently, understanding how PARs act is of great biological importance. Recently, we have shown that the activity of the PAR signalling component, aPKC-kinase, is not only critical for the polarisation programme but also creates the asymmetric domain of active PARs needed for the development of the early embryo. We are seeking an enthusiastic student keen to reveal the molecular mechanisms underlying this novel aPKC function. We will use a multidisciplinary approach, including genetic screens, proteomics, biochemical assays, genome editing, mathematical modelling and cutting-edge microscopy analyses. Studies will be performed in nematode C. elegans and mammalian model systems.
