Shields up: the Tup1-Cyc8 repressor complex blocks coactivator recruitment.
The Tup1-Cyc8 complex is responsible for repression of a large and diverse collection of genes in Saccharomyces cerevisiae. The predominant view has been that Tup1-Cyc8 functions as a corepressor, actively associating with regulatory proteins and organizing chromatin to block transcription. A new study by Wong and Struhl in this issue of Genes & Development (pp. 2525-2539) challenges nearly 20 ...
متن کاملCollagen corneal shields.
Collagen corneal shields were developed as a corneal bandage lens and are currently indicated for ocular surface protection following surgery and in traumatic and nontraumatic corneal conditions. Collagen shields are manufactured from porcine or bovine collagen and three different collagen shields are currently available with dissolution times of 12, 24, and 72 hours. The theoretical, experimen...
متن کاملProtein shields for dehydration
Turning motor into anchor A motor in the fl y oocyte is turned into a static anchor to hold its polarity-inducing cargo in place, say Renald Delanoue, Bram Herpers, Jan Soetaert, Ilan Davis (University of Oxford, UK), and Catherine Rabouille (University Medical Centre Utrecht, Netherlands). The switch from motor to anchor is thrown by an RNA-binding protein called Squid. Squid mutants were orig...
متن کاملHow Concentration Shields Against Distraction
In this article, we outline our view of how concentration shields against distraction. We argue that higher levels of concentration make people less susceptible to distraction for two reasons. One reason is that the undesired processing of the background environment is reduced. For example, when people play a difficult video game, as opposed to an easy game, they are less likely to notice what ...
متن کاملOxygen permeability of collagen shields.
The oxygen permeability (Dk) of ten 24-hr collagen shields was measured directly by polarographic methodology at approximately 2 hr of hydration. Edge and boundary effects were included in the calculations. Dk was found to be approximately 26 x 10(-11) cm ml O2/sec ml mmHg at 35 degrees C. Mean water content of the shields was 65.7% (SD = 1.0%) as measured by a hand refractometer. Therefore, th...
