SummaryOur group is interested is the regulation of mRNA translation during embryo development and disease. In particular, we investigate how RNA-binding proteins (RBPs) regulate translation and how this is connected with general cell homeostasis and cancer progression. As RBPs are capable of binding hundreds of transcripts, their alterations often have widespread consequences in gene expression and may lead to cell malfunction. Progress during 2014 include collaborative work showing new interactions by which general RBPs cooperatively bind to RNA (Figure 1), and novel roles for the regulator UNR in X-chromosome dosage compensation (Figure 2). The data illustrate and expand the plasticity of RBPs for gene regulation.
