Aberrant folding and fibrillar aggregation by polyglutamine (polyQ) expansion proteins are associated with cytotoxicity in Huntington's disease and other neurodegenerative disorders. Hsp70 chaperones have an inhibitory effect on fibril formation and can alleviate polyQ cytotoxicity. Here we show that the cytosolic chaperonin, TRiC, functions synergistically(More)
Serum response factor transcriptional activity is controlled through interactions with regulatory cofactors such as the coactivator MAL/MRTF-A (myocardin-related transcription factor A). MAL is itself regulated in vivo by changes in cellular actin dynamics, which alter its interaction with G-actin. The G-actin-sensing mechanism of MAL/MRTF-A resides in its(More)
Subcellular localization of the actin-binding transcriptional coactivator MRTF-A is controlled by its interaction with monomeric actin (G-actin). Signal-induced decreases in G-actin concentration reduce MRTF-A nuclear export, leading to its nuclear accumulation, whereas artificial increases in G-actin concentration in resting cells block MRTF-A nuclear(More)
Mean rotation induces dynamical effects on turbulence that enter the transport equations through the non-local pressure-strain-rate correlation. It was shown in Kassinos & Reynolds (1994) and Reynolds & Kassinos (1995) that, to describe this effect accurately using one-point turbulence statistics, a turbulence model should include the transport equations(More)
Monoclonal antibodies to five nonoverlapping antigenic domains of woodchuck hepatitis virus surface antigen (WHsAg) were used to develop site-specific radioimmunoassays. The assays were based on the solid-phase sandwich principle in which different combinations of individual domain-specific antibodies were used as immunoadsorbents and radioiodinated probes.(More)
