RNA aptamers-artificially created RNAs with high affinity and selectivity for their target ligand generated from random sequence pools-are versatile tools in the fields of biotechnology and medicine. On a more fundamental level, they also further our general understanding of RNA-ligand

The H1069Q substitution is the most frequent mutation of the Cu transporter ATP7B that causes Wilson disease in the Caucasian population. ATP7B localizes to the Golgi complex in hepatocytes, but, in the presence of excessive Cu, it relocates to the

With current available assay formats using either immobilized protein (ELISA, enzyme-linked immunosorbent assay) or immunostaining of fixed cells for primary monoclonal antibody (mAb) screening, researchers often fail to identify and characterize antibodies that recognize the native conformation of cell-surface antigens.

N-myristoylation is a ubiquitous class of protein lipidation across eukaryotes and N-myristoyl transferase (NMT) has been proposed as an attractive drug target in several pathogens. Myristoylation often primes for subsequent palmitoylation and stable membrane attachment, however, growing evidence suggests additional

We explore a strategy to substantially increase the half-life of recombinant proteins by genetic fusion to FcIII, a 13-mer IgG-Fc domain binding peptide (IgGBP) originally identified by DeLano and co-workers at Genentech [DeLano WL, et al. (2000) Science 287:1279-1283]. IgGBP

In mammals, the emergence of totipotency after fertilization involves extensive rearrangements of the spatial positioning of the genome1,2. However, the contribution of spatial genome organization to the regulation of developmental programs is unclear3. Here we generate high-resolution maps of genomic
Advanced science (Weinheim, Baden-Wurttemberg, Germany), 5(8), 1800240-1800240 (2018-08-22)
An amphipathic leucine (L) and lysine (K)-rich α-helical peptide is multimerized based on helix-loop-helix structures to maximize the penetrating activities. The multimeric LK-based cell penetrating peptides (LK-CPPs) can penetrate cells as protein-fused forms at 100-1000-fold lower concentrations than Tat peptide.
Biophysical journal, 89(5), L37-L39 (2005-10-04)
A series of DNA molecules labeled with 5-carboxytetramethylrhodamine (5-TAMRA) and the small nitroxide radical TEMPO were synthesized and tested to investigate whether the intramolecular quenching efficiency can be used to measure short intramolecular distances in small ensemble and single-molecule experiments.
Analytical biochemistry, 385(1), 85-93 (2008-11-20)
The bisubstrate fluorescent probe ARC-583 (Adc-Ahx-(D-Arg)(6)-d-Lys(5-TAMRA)-NH2) and its application for the characterization of both ATP- and protein/peptide substrate-competitive inhibitors of protein kinases PKA (cyclic AMP-dependent protein kinase) and ROCK (rho kinase) in fluorescence polarization-based assay are described. High affinity of
Enhanced Cellular Transduction of Nanoparticles Resistant to Rapidly Forming Plasma Protein Coronas.
Advanced biosystems, 4(10), e2000162-e2000162 (2020-09-15)
Nanoparticles (NPs) are increasingly being developed as biomedical platforms for drug/nucleic acid delivery and imaging. However, in biological fluids, NPs interact with a wide range of proteins that form a coating known as protein corona. Coronae can critically influence self-interaction
Journal of cell science, 133(5) (2020-02-02)
Phagocytosis is a dynamic process central to immunity and tissue homeostasis. Current methods for quantification of phagocytosis largely rely on indirect or static measurements, such as target clearance or dye uptake, and thus provide limited information about engulfment rates or
Cholesterol-Enriched Domain Formation Induced by Viral-Encoded, Membrane-Active Amphipathic Peptide.
Biophysical journal, 110(1), 176-187 (2016-01-09)
The α-helical (AH) domain of the hepatitis C virus nonstructural protein NS5A, anchored at the cytoplasmic leaflet of the endoplasmic reticulum, plays a role in viral replication. However, the peptides derived from this domain also exhibit remarkably broad-spectrum virocidal activity
Cell, 183(7), 1772-1784 (2020-12-17)
The association of nuclear DNA with histones to form chromatin is essential for temporal and spatial control of eukaryotic genomes. In this study, we examined the physical state of condensed chromatin in vitro and in vivo. Our in vitro studies demonstrate that self-association

Intraneuronal accumulation of amyloid-β(1-42) (Aβ1-42) is one of the earliest signs of Alzheimer's disease (AD). Cell surface heparan sulfate proteoglycans (HSPGs) have profound influence on the cellular uptake of Aβ1-42 by mediating its attachment and subsequent internalization into the cells.
Acta biomaterialia, 23, 263-270 (2015-05-20)
Silica-based nanomaterials have demonstrated great potential in biomedical applications due to their chemical inertness. However, the degradability and endosomal trapping issues remain as rate-limiting barriers during their innovation. In this study, we provide a simple yet novel sol-gel approach to
Analytical biochemistry, 340(1), 165-170 (2005-04-02)
A fluorometric assay for measuring protein kinase activity has been developed. The assay is based on the separation of fluorescently marked substrate 5-carboxytetramethylrhodamine-kemptide (5-TAMRA-kemptide) from its phosphorylated counterpart by TLC and quantification of the product ratiometrically by fluorescence imaging. The
