Wallace S Ip

Professional Summary

Wallace Ip, Professor of Cancer and Cell Biology received his undergraduate and graduate education at the Illinois Institute of Technology. He was a postdoctoral fellow at SUNY Downstate Medical Center and Washington University. He joined the University of Cincinnati as a faculty member in 1985. He serves as Director of the Center for Biological Microscopy in addition to his research activities. The Ip laboratory's studies focus on a disease called neurofibromatosis type 2 (NF2), whose clinical manifestation is nervous system tumors called schwannomas and meningiomas. Loss of the NF2 gene product, merlin, leads to tumor formation; thus merlin is a classic tumor suppressor. Merlin is related to a family of molecules (the ERM family) that link the actin cytoskeleton to the plasma membrane. They have recently discovered that merlin is largely localized to specialized plasma membrane microdomains called lipid rafts, where numerous signal transduction events are known to occur. They have now identified a number of merlin interacting partners within lipid rafts, and are studying how they modulate merlin function. These studies should allow merlin to be placed in the context of the vast and complex signal transduction network that regulates cell growth.

Research and Practice Interests

Our studies focus on the protein product of the neurofibromatosis type II (NF2) gene. This protein, merlin, belongs to a family of molecules that link the cytoskeleton to the plasma membrane (the ERM family). Interestingly, it is the only member of this family that functions as a tumor suppressor - loss of merlin leads to formation of nervous system tumors called schwannomas and meningiomas. We recently discovered that merlin is largely localized to lipid rafts, specialized plasma membrane microdomains that serve as physical platforms for signal transduction. This is the first tumor suppressor molecule known to reside in lipid rafts, and its residence appears to be constitutive, i.e., regardless of whether merlin is in the active, growth suppressive conformation or the inactive, growth permissive conformation. Current efforts in the lab are centered around identifying merlin's interacting partners, and the signaling pathways in which merlin participates.
