Tra1 has specific regulatory roles, rather than global functions, within the SAGA co-activator complex.

The SAGA complex is a conserved, multifunctional co-activator that has broad roles in eukaryotic transcription. Previous studies suggested that Tra1, the largest SAGA component, is required either for SAGA assembly or for SAGA recruitment by DNA-bound transcriptional activators. In contrast to Saccharomyces cerevisiae and mouse, a tra1Δ mutant is viable in Schizosaccharomyces pombe, allowing us...

Domains of Tra1 important for activator recruitment and transcription coactivator functions of SAGA and NuA4 complexes.

The Tra1 protein is a direct transcription activator target that is essential for coactivator function of both the SAGA and NuA4 histone acetyltransferase (HAT) complexes. The ∼400-kDa Saccharomyces cerevisiae Tra1 polypeptide and its human counterpart TRRAP contain 67 or 68 tandem α-helical HEAT and TPR protein repeats that extend from the N terminus to the conserved yet catalytically inactive...

Nipped-A, the Tra1/TRRAP subunit of the Drosophila SAGA and Tip60 complexes, has multiple roles in Notch signaling during wing development.

The Notch receptor controls development by activating transcription of specific target genes in response to extracellular signals. The factors that control assembly of the Notch activator complex on target genes and its ability to activate transcription are not fully known. Here we show, through genetic and molecular analysis, that the Drosophila Nipped-A protein is required for activity of Not...

Providing complex (rather than complicated) chronic care.

With health care reform underway, the results of the study by Sharma et al emphasize the foundational role of primary care in our multimorbiditybased chronic care system. They found that the majority of patients with 14 high-cost chronic conditions saw general rather than specialist physicians. They suggest that the level of dependence that this chronically ill population has on primary care ma...

Co-infection of Ticks: The Rule Rather Than the Exception.

INTRODUCTION Ticks are the most common arthropod vectors of both human and animal diseases in Europe, and the Ixodes ricinus tick species is able to transmit a large number of bacteria, viruses and parasites. Ticks may also be co-infected with several pathogens, with a subsequent high likelihood of co-transmission to humans or animals. However few data exist regarding co-infection prevalences, ...
