A genetic analysis of mortality in pigs.

abstract：:Constitutive transport of cellular materials is essential for cell survival. Although multiple small GTPase Rab proteins are required for the process, few regulators of Rabs are known. Here we report that EAT-17, a novel GTPase-activating protein (GAP), regulates RAB-6.2 function in grinder formation in Caenorhabditis...

abstract：:Nucleosome-depleted regions (NDRs) are present immediately adjacent to the transcription start site in most eukaryotic promoters. Here we show that NDRs in the upstream promoter region can profoundly affect gene regulation. Chromatin at the yeast HO promoter is highly repressive and numerous coactivators are required ...
