Research Focus
My group is interested in signalling pathways that promote colorectal tumorigenesis and we study (i) the alternative splice variant Rac1b overexpressed in tumours, (ii) the effect of activated b-catenin/TCF signalling on splicing, (iii) the effect on splicing of exonic missense mutations diagnosed by our department in colorectal tumour suppressor genes, and (iv) the role of a novel cell-cycle regulating protein that co-immunoprecipitates with cdc5L and Prp19.
