PhD candidate (f/m) – for the research project in „Cooperation between microtubule polymerases and gamma-tubulin “

About the project:


Microtubules are highly dynamic polymers with essential functions in chromosome segregation in mitosis and meiosis, cell migration, transport and ciliogenesis. Drugs that target microtubules are used in cancer therapy indicating the therapeutic potential of the microtubule system.


Microtubules assemble through the polymerisation of tubulin at centrosomes. The gamma-tubulin complex (gamma-TuC) cooperates with the XMAP215/ch-TOG/Stu2 family of microtubule polymerases in microtubule assembly. Recently, we have shown (eLife, under revision) that the microtubule polymerase Stu2 directly interacts with the gamma-TuC in order to add the first tubulin molecules to the gamma-tubulin ring. Here we will extend this work to the structural and functional analysis of gamma-tubulin complexes with bound microtubule polymerase.
