Structure and function analysis of the Merlin Sip1 complex

  • Author / Creator

  • Mutations in the NF2 gene lead to the disease Neurofibromatosis Type II which is characterized by the formation of multiple tumours in the central nervous system. The NF2 gene encodes the protein Merlin. Merlin interacts with a number of different proteins and these interactions may be important for Merlin tumour suppressor function. Amongst these proteins, EBP50 has been identified as a candidate scaffold protein. In this thesis, I identified a potential novel binding site in Drosophila Merlin to the Drosophila EBP50 homolog, Sip1. I determined that this potential novel binding site is both necessary and sufficient for binding in vitro. In addition, a conserved potential novel phosphorylation site is also identified in this region and may be involved in the regulation of the Merlin Sip1 interaction. These results suggest that a regulatory protein complex may be involved in Merlin tumour suppressor activity.
