Molecular and functional analysis of cadherin-based adherens junctions.
Adherens junctions are specialized forms of cadherin-based adhesive contacts important for tissue organization in developing and adult organisms. Cadherins form protein complexes with cytoplasmicExpand

A type III secretion system in Vibrio cholerae translocates a formin/spire hybrid-like actin nucleator to promote intestinal colonization.
We have previously characterized a non-O1, non-O139 Vibrio cholerae strain, AM-19226, that lacks the known virulence factors but contains components of a type III secretion system (T3SS). In thisExpand

Lateral clustering of the adhesive ectodomain: a fundamental determinant of cadherin function
BACKGROUND Classical cadherin-based cellular adhesion is mediated by a multicomponent protein complex that links the adhesive binding activity of the cadherin ectodomain to the actin cytoskeleton.Expand

A quantitative analysis of contractility in active cytoskeletal protein networks.
Cells actively produce contractile forces for a variety of processes including cytokinesis and motility. Contractility is known to rely on myosin II motors which convert chemical energy from ATPExpand

α-Actinin-4/FSGS1 is required for Arp2/3-dependent actin assembly at the adherens junction
α-Actinin-4 plays an important role in coupling actin nucleation to assembly at cadherin-based cell–cell adhesive contacts.

Rapid actin monomer–insensitive depolymerization of Listeria actin comet tails by cofilin, coronin, and Aip1
Actin filaments in cells depolymerize rapidly despite the presence of high concentrations of polymerizable G actin. Cofilin is recognized as a key regulator that promotes actin depolymerization. InExpand

Actin disassembly by cofilin, coronin, and Aip1 occurs in bursts and is inhibited by barbed-end cappers
Turnover of actin filaments in cells requires rapid actin disassembly in a cytoplasmic environment that thermodynamically favors assembly because of high concentrations of polymerizable monomers. WeExpand

Lateral dimerization is required for the homophilic binding activity of C-cadherin
Regulation of cadherin-mediated adhesion can occur rapidly at the cell surface. To understand the mechanism underlying cadherin regulation, it is essential to elucidate the homophilic bindingExpand

Caspase-11 regulates cell migration by promoting Aip1–Cofilin-mediated actin depolymerization
Coordinated regulation of cell migration, cytokine maturation and apoptosis is critical in inflammatory responses. Caspases, a family of cysteine proteases, are known to regulate cytokine maturationExpand

Regulation of C-cadherin function during activin induced morphogenesis of Xenopus animal caps
Treatment of Xenopus animal pole tissue with activin results in the induction of mesodermal cell types and a dramatic elongation of the tissue. The morphogenetic movements involved in the elongationExpand
