Regulation of ARE transcript 3? end processing by the yeast Cth2 mRNA decay factor
2008-11-19

Regulation of mRNA decay is an important step modulating gene expression. The stability of numerous eukaryotic mRNAs is controlled by adenosine/uridine-rich elements (AREs) located in their 3?UTR. In Saccharomyces cerevisiae, the Cth2 protein stimulates the decay of target ARE mRNAs on iron starvation. Cth2, and its mammalian homologue tristetraprolin, contains a characteristic tandem CCCH ...

Solution structure of the U2 snRNP protein Rds3p reveals a knotted zinc-finger motif.
2008-07-08

Rds3p, a component of the U2 snRNP subcomplex SF3b, is essential for pre-mRNA splicing and is extremely well conserved in all eukaryotic species. We report here the solution structure of Rds3p, which reveals an unusual knotted fold unrelated to previously known knotted proteins. Rds3p has a triangular shape with a GATA-like zinc finger at each vertex. ...

The ACT Hand: Design of the Skeletal Structure
2004-01-01

Robotic hands built for manipulation are often anthropomorphic but not anatomically accurate. We are constructing an anatomically-correct testbed (ACT) of the human hand to understand its mechanisms, function, and control. We have previously demonstrated that an accurate model of the extensor mechanism in the ACT Hand is crucial in realizing the human-like finger movements. ...
