Research group(s)

  • Transport and Signal Transduction of Surface Receptors
    Head: Ruth Herbst
    Research Area: We are interested in how receptor tyrosine kinases induce intracellular signaling cascades thereby regulating crucial cellular process including cell proliferation, differentiation and survival. Further, we are interested in trafficking processes such as endocytosis and recycling of surface proteins. We study process in the muscle and in immune cells

Research interests

My work is focused on characterizing how receptor tyrosine kinases induce intracellular signaling cascades thereby regulating crucial cellular processes including cell proliferation, differentiation and function. My long-term interests center around the receptor tyrosine kinase MuSK. As postdoctoral fellow and subsequently as independent group leader, together with my laboratory, I made important contributions to the function of MuSK and to the characterization of downstream signaling events. More recently I have also become interested in protein trafficking and the interplay between signaling and protein endocytosis. In this respect, we have identified a novel guanidine nucleotide exchange factor with potential function in T cell responses during inflammatory conditions.

Techniques, methods & infrastructure

Experimental strategies include muscle cell cultures and their manipulation (retroviral-mediated gene transduction), confocal microscopy as well as in vivo imaging and analysis of transgenic animal models. Biochemistry, molecular biology and cell biology techniques complete our approaches.
