Myotonic dystrophy (DM) is an autosomal dominant neuromuscular disease that is associated with a (CTG)n repeat expansion in the 3'-untranslated region of the myotonin protein kinase (Mt-PK) gene. This study reports the isolation and characterization of a (CUG)n triplet repeat pre-mRNA/mRNA binding protein that may play an important role in DM pathogenesis.(More)
To study the functions of heterogeneous nuclear ribonucleoproteins (hnRNPs), we have characterized nuclear polyadenylated RNA-binding (Nab) proteins from Saccharomyces cerevisiae. Nab1p, Nab2p, and Nab3p were isolated by a method which uses UV light to cross-link proteins directly bound to poly(A)+ RNA in vivo. We have previously characterized Nab2p, and(More)
Recent reports indicate that proteins which directly bind to nascent RNA polymerase II transcripts, the heterogeneous nuclear ribonucleoproteins (hnRNPs), play an important role in both transcript-specific packaging and alternative splicing of pre-mRNAs. Here we describe the isolation and characterization of a group of abundant hnRNPs, the M1-M4 proteins,(More)
A variety of nuclear ribonucleoproteins are believed to associate directly with nascent RNA polymerase II transcripts and remain associated during subsequent nuclear RNA processing reactions, including pre-mRNA polyadenylation and splicing as well as nucleocytoplasmic mRNA transport. To investigate the functions of these proteins by using a combined(More)
A variety of approaches have been described for the modification of synthetic, water soluble polymers with hydrolytically degradable bonds and terminal vinyl groups that can be crosslinked in situ by photo- or redox-initiated free radical polymerization. However, changes in macromer concentration, functionality, and molecular weight commonly used to achieve(More)
Hip joint implant surgery is becoming common not only in old aged people, but also in comparatively younger persons. The load experienced by the hip implant is of fluctuating nature, and hence, the prediction of fatigue life of the hip implant is of utmost importance. This paper deals with the preparation of finite element model, its validation through(More)
