Research interest:
Cilia and eukaryotic flagella (interchangeable terms) are microtubule-based cellular surface protrusions. They play essential roles in cell motility, signaling to regulate various biological processes including sensory transduction, development, tissues and organ homeostasis. Thus, defects in the structure and/or function of cilia/flagella have been implicated in various human disorders including renal diseases, respiratory disorders, developmental abnormality and even diabetes. The structural integrity and proper function of cilia/flagella requires coordinated regulation of the assembly and disassembly of cilia.
We are using Chlamydomonas, a uni-cellular green alga, as a model organism to study the mechanisms underlying the assembly and disassembly of cilia. Previously we have identified an aurora-like protein kinase - CALK, which is required for flagellar disassembly. Recently, we discovered that microtubule depolymerizing kinesin-CrKinesin13 is phosphorylated and is involved in flagellar assembly and disassembly. Currently we focus on the regulation control of CALK and CrKinesin13. Since cilia disassembly occurs prior to cell division, we also aim to understand how cilia disassembly regulates the cell cycle progression. In addition, we are characterizing several mutants defective in the assembly and disassembly of flagella. These defective genes may be involved in the regulation of Intraflagellar transport, a bidirectional transport process between the flagellar tip and the cell body, which is required for flagellar assembly and disassembly. Since cilia and eukaryotic flagella are conserved cellular organelles, our research findings will have great impact on understanding cilia-related human disorders and may provide guidance on possible diagnostics and treatment for these diseases.
