Research areas and projects:

Miao Lab research mainly focuses on studying the mechanisms of actin assembly in polarized fungal growth and plant immunity. Miao Lab interested in how diverse extracellular and intracellular signals regulate actin assembly underlying diverse physiological and pathological processes in eukaryotic cells. Actin filament assembly contributes to the multiple cellular pathways pleiotropically, by its dynamic assembly and disassembly upon cellular needs and specific stimuli, such as the activation of polarized cell growth or the host immune responses during defense mechanisms against pathogenic attack. In the much crowd intracellular environment, actin-binding proteins (ABPs) precisely regulate the dynamics assembly and re-organization of actin networks, in cooperative and competitive manners. We are particularly interested in how the intrinsically disordered regions (IDRs) of ABPs perceive the signals to trigger re-organization of actin assembly, by regulating the protein dynamics, protein conformation, and protein-protein interactions, via interdisciplinary approaches, such as biochemical assay, advanced cell imaging, genetic approaches.

Our lab is interested in how eukaryotic cells dynamically reorganize their actin cytoskeletons to power endocytosis, polarized delivery of vesicles for cell growth, cell movement, and cell division. Our research is focus on understanding of how different actin interacting proteins (AIPs) are regulated to assemble different types of actin arrays, nucleated by Arp2/3 complex and formins, in the same cytoplasm during these processes, and at different stages of the cell cycle.

We are using multi-disciplinary approach including reconstitution of actin assembly in cell extracts, live-cell imaging, genetics, biochemistry, super-resolution microscopy, and mass spectrometry to address these questions from the molecular to cellular level. Our working systems include budding yeast, plants, and cultured mammalian cell lines.

One of our major goals is to determine the function and molecular fundamentals of several key AIPs that regulate the dynamics of different actin arrays at specific cell cycle stage or a particular physiological conditions, e.g. stress response. And we also aim to reconstitute such actin assembly by our cell-extract based system at these particular conditions.
