Selective ubiquitin-dependent autophagy plays a pivotal role in the elimination of protein aggregates, assemblies, or organelles and counteracts the cytotoxicity of proteins linked to neurodegenerative diseases. Following substrate ubiquitylation, the cargo is delivered to autophagosomes involving adaptors like human p62 that bind ubiquitin and the autophagosomal ubiquitin-like protein Atg8/LC3...

Amyloid precursor protein intracellular domain (AICD) is one of the potential candidates in deciphering the complexity of Alzheimer's disease. It plays important roles in determining cell fate and neurodegeneration through its interactions with several adaptors. The presence or absence of phosphorylation at specific sites determines the choice of partners. In this study, we identified 20 novel ...

Peritoneal dialysis catheter ruptures have been managed by immediate removal and subsequent reinsertion of the catheter which inevitably entails interruption in peritoneal dialysis and a need for vascular access. A 36-year-old man on continuous ambulatory peritoneal dialysis complaining of dialysate leakage was found to have a small rupture near the outer cuff of the peritoneal dialysis cathete...

To initiate mitochondrial fission, dynamin-related proteins (DRPs) must bind specific adaptors on the outer mitochondrial membrane. The structural features underlying this interaction are poorly understood. Using yeast as a model, we show that the Insert B domain of the Dnm1 guanosine triphosphatase (a DRP) contains a novel motif required for association with the mitochondrial adaptor Mdv1. Mut...

We describe a method for the construction of large DNA fragment libraries in plasmid vectors, in which complementary, single-stranded extensions are ligated onto both vector and insert DNA using un-phosphorylated adaptor oligonucleotides. Special consideration has been taken of the requirements of expression screening as follows: cDNA synthesis using random oligonucleotide primers is described ...

By only sending the parity bits, joint source-channel coding can be natively achieved with lowdensity parity-check codes. However, the code ensemble design of optimal low-density parity-check codes for joint source-channel coding over asymmetric communication channels is difficult. To circumvent such a difficulty, source-channel adaptors is proposed in this paper. By using the source-channel ad...

Many genome walking methods based on polymerase chain reaction (PCR) are available, including those with and without restriction enzyme modification. Nevertheless, these methods suffer from low reproducibility, inefficiency, and non-specificity. Here, we present a traceable and efficient PCR strategy: randomly broken fragment PCR with 5' end-directed adaptor for genome walking. The genome is fi...

The Nef protein is unique to primate lentiviruses and is closely linked to accelerated pathogenesis in both human and monkey hosts. Nef acts to down-regulate CD4 and MHC class I, two receptors important for immune function. A recent report demonstrated the presence of two tyrosine motifs in SIV Nef that contribute to its ability to down-regulate CD4 and to associate with clathrin adaptors. Thes...

The results of an investigation in developing a generalized toolkit for Quadtree based Finite Volume models, exemplarily applied on the Shallow Water Equations, are given in this report. The developed application model: (i) discretizes a given topography using a quadtreebased grid system and (ii) solves the Shallow Water Equations by a numerical method based on the Finite Volume Method on the a...
