Research Areas

Cell signalling; Regulation of actin cytoskeleton; Rho GTPases, their effectors and regulators

Research Interests

Our laboratory is interested in the signal transduction events involving small GTPases of the Rho family, their regulators and effectors. These proteins play key roles in transducing extracellular stimuli into distinct responses including cell shape changes, cell motility, adhesion, cell division and phagocytosis. The emphasis of our current research is on the kinase PAK, its interacting protein PIX and a family of serine/ threonine phosphataes of the PP2C family, POPXs.

Biography

Dr Koh did her undergraduate studies at the Department of Chemistry at the National University of Singapore. After completing her Ph.D. with Sydney Brenner at the University of Cambridge, she returned to Singapore to work on Fugu genomics at the Institute of Molecular and Cell Biology. She later moved to Louis Lim’s laboratory at the same institute to study small GTPases-mediated cell signaling. In 2004, Dr Koh started her own laboratory at the School of Biological Sciences, Nanyang Technological University. Dr Koh is also a Principal Investigator at MBI.
