What is the role of cortactin in actin polymerization?
What is the role of cortactin in actin polymerization? Cortactin is a class II nucleation promoting factor (NPF) that binds to actin filaments and influences their stability. Cortactin specifically stabilizes Arp2/3-mediated branch points along [...]
What is the role of formin in actin polymerization?
What is the role of formin in actin polymerization? Formins promote the elongation of pre-existing filaments by removing barbed end capping proteins and forming a sleeve around the actin subunits. Formins are also capable [...]
What is the steady state phase of actin polymerization?
What is the steady state phase of actin polymerization? In the steady state phase, the filament dynamics enter a state of equilibrium where monomer disassembly from the (-) end and polymerization at the (+) [...]
What factors influence actin filament length and treadmilling?
What factors influence actin filament length and treadmilling? Several factors influence actin filament length and treadmilling. ATP binding on G-actin and free ATP-G-actin concentration ATP-binding on actin subunits modulates the dynamics of filament assembly, [...]
Actin Crosslinking
Actin Crosslinking Crosslinking of actin filaments is a critical step in cell motility and is a fundamental process in filopodia protrusion and lamellipodia formation. Smaller cross-linking proteins that are more globular (e.g. fascin) [...]
What factors regulate actin filament polymerization?
What factors regulate actin filament polymerization? Nucleation Promoting Factors (NPFs) (e.g. WASP, Scar/WAVE) modulate actin filament nucleation by bringing together actin monomers and pre-existing actin filaments, for example, during filopodial initiation where they recruit [...]

I decided to switch into the world of biology after I received my BS in chemistry from Zhejiang University. With the interest in things happening inside nucleus, I joined Prof. Shiva’s lab as a graduate student, to study the role of external mechanical signals on gene regulation in eukaryotic cells. During my first one and a half years I developed a method to visualize active transcription sites on open chromatin spreads using super-resolution microscopy. Presently I’m studying the role of cell geometric constraints on 3D organization of chromosomes by using multiple techniques such as fluorescence in situ hybridization (FISH), confocal imaging, and super-resolution imaging.
