Uniform Equicontinuity for a family of Zero Order operators approaching the fractional Laplacian [PDF]

, 2014
In this paper we consider a smooth bounded domain $\Omega \subset \R^N$ and a parametric family of radially symmetric kernels $K_\epsilon: \R^N \to \R_+$ such that, for each $\epsilon \in (0,1)$, its $L^1-$norm is finite but it blows up as $\epsilon \to ...

Non-homogeneous problem for fractional Laplacian involving critical Sobolev exponent

Electronic Journal of Differential Equations, 2017
In this article, we study the existence of positive solutions for the nonhomogeneous fractional equation involving critical Sobolev exponent $$\displaylines{ (-\Delta)^{s} u +\lambda u=u^p+\mu f(x), \quad u>0\quad \text{in } \Omega,\cr u =0, \quad \

Gradient schemes for the Stefan problem [PDF]

, 2013
We show in this paper that the gradient schemes (which encompass a large family of discrete schemes) may be used for the approximation of the Stefan problem $\partial_t \bar u - \Delta \zeta (\bar u) = f$.

The membrane-associated proteins FCHo and SGIP are allosteric activators of the AP2 clathrin adaptor complex

eLife, 2014
The AP2 clathrin adaptor complex links protein cargo to the endocytic machinery but it is unclear how AP2 is activated on the plasma membrane. Here we demonstrate that the membrane-associated proteins FCHo and SGIP1 convert AP2 into an open, active ...

Spatiotemporal Control of Lipid Conversion, Actin-Based Mechanical Forces, and Curvature Sensors during Clathrin/AP-1-Coated Vesicle Biogenesis

Cell Reports, 2017
Clathrin/adaptor protein-1-coated carriers connect the secretory and the endocytic pathways. Carrier biogenesis relies on distinct protein networks changing membrane shape at the trans-Golgi network, each regulating coat assembly, F-actin-based ...

Through its F-BAR and RhoGAP domains, Rgd1p acts in different polarized growth processes in budding yeast

Communicative & Integrative Biology, 2009
Protein domain architecture can be used to construct supramolecular structures, to carry out specific functions and to mediate signaling in prokaryotic and eukaryotic cells. The Rgd1p protein of budding yeast contains two domains with different functions in the cell: the F-BAR and RhoGAP domains.

IRSp53 mediates podosome formation via VASP in NIH-Src cells.

PLoS ONE, 2013
Podosomes are cellular "feet," characterized by F-actin-rich membrane protrusions, which drive cell migration and invasion into the extracellular matrix.

A BAR homology domain containing protein, EhABP is the novel interactor of EhAK7, an aurora kinase homolog in E. histolytica

Current Research in Biotechnology
Biomolecular interactions among proteins are fundamental for all cellular functions. The chromosome segregation proteins are the key regulators of inherent functions in the living cells. Aurora kinases have drawn much interest as possible drug targets in

Physicochemical Analysis from Real-Time Imaging of Liposome Tubulation Reveals the Characteristics of Individual F-BAR Domain Proteins

Langmuir, 2012
The Fer-CIP4 homology-BAR (F-BAR) domain, which was identified as a biological membrane-deforming module, has been reported to transform lipid bilayer membranes into tubules. However, details of the tubulation process, the mechanism, and the properties of the generated tubules remain unknown.

Phosphorylation of the F-BAR protein Hof1 drives septin ring splitting in budding yeast

Nature Communications
A double septin ring accompanies cytokinesis in yeasts and mammalian cells. In budding yeast, reorganisation of the septin collar at the bud neck into a dynamic double ring is essential for actomyosin ring constriction and cytokinesis.
