Direct and Inverse Approximation Theorems for Baskakov Operators with the Jacobi-Type Weight

open access: yesAbstract and Applied Analysis, 2011
We introduce a new norm and a new K-functional Kφλ(f;t)w,λ. Using this K-functional, direct and inverse approximation theorems for the Baskakov operators with the Jacobi-type weight are obtained in this paper.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Estimating the $K$ function of a point process with an application to cosmology

open access: yesThe Annals of Statistics, 2000
Motivated by the study of an important data set for understanding the large-scale structure of the universe, this work considers the estimation of the reduced second moment function, or K-function, of a stationary point process observed over a large number of segments of possibly varying lengths.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Unique Regulation of Na-K-ATPase during Growth and Maturation of Intestinal Epithelial Cells

open access: yesCells, 2019
Na-K-ATPase on the basolateral membrane provides the favorable transcellular Na gradient for the proper functioning of Na-dependent nutrient co-transporters on the brush border membrane (BBM) of enterocytes.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Molecular and functional expression of high conductance Ca2+ activated K+ channels in the eel intestinal epithelium

open access: yes, 2008
Several types of K+ channels have been identified in epithelial cells. Among them high conductance Ca2+- activated K+ channels (BK channels) are of relevant importance for their involvement in regulatory volume decrease (RVD) response following ...

Characterization of HERV-K (HML-2) Rec proteins encoded in the human genome and their post-transcriptional function

open access: yesJournal of Virology
Human endogenous retrovirus K (HERV-K) proviruses of the HML-2 subgroup are the most recently integrated retroviral elements within the human genome. The HERV-K Rec protein, a functional homolog of HIV Rev, is essential for the expression of viral mRNAs ...
