The subcellular localization of a protein can be very informative in identifying its function and in understanding the regulatory mechanisms by which it is controlled. Past efforts to define protein localization have typically entailed methods of immunological and fluorescence-based detection applied to a limited number of gene products. Several current studies are shifting this paradigm – utilizing traditional and novel approaches in molecular biology, proteomics, histochemistry and bioinformatics to define protein localization on a proteome-wide scale. Selected studies highlighting each of these approaches are presented here as an overview of the diverse avenues by which protein localization may be investigated for the identification of new drug targets. 相似文献

No Nogo: now where to go? 总被引:12,自引:0,他引:12
Nogo-A, a reticulon protein expressed by oligodendrocytes, contributes to the axonal growth inhibitory action of central myelin in growth cone collapse and neurite outgrowth in vitro assays, and antibody and inhibitor studies have implicated a role for Nogo in regeneration in the adult CNS in vivo. Three independent labs have now produced Nogo knockout mice with, quite unexpectedly, three different regeneration phenotypes. 相似文献

Aquaculture has been one of the most rapid and technically innovative of food production sectors globally, with significant investment, scientific and technical development and production growth in many parts of the world over the past two decades. While this has had a significant effect on the global supply of aquatic food products and had an important impact in rural and urban food supply and employment in many developing economies, growth and increasing internationalization has not been without concern for natural resource use, environmental impact and social disruption. The expectations for production and diversification are now significant and while the scientific and technical means are already available to meet much of the intended targets, practical constraints of investment, profitability, resource access and system efficiency are likely to become far more important constraints for the future. This review offers a contemporary perspective on the ways in which the sector might develop, its interactions with constraints and the strategies that may be required to ensure that future development is both positive and sustainable. 相似文献

Following the practical success attributed to avidin-biotin technology, researchers are now returning to the basics to try to understand the structural and functional requirements for the high-affinity avidin-biotin interaction. 相似文献

Despite tremendous progress in the study of voltage-gated channels, the molecular mechanism underlying voltage sensing has remained a matter of debate. We review five new studies that make major progress in the field. The studies employ a battery of distinct approaches that have the common aim of measuring the motion of the voltage sensor. We interpret the results in light of the recent crystal structure of the mammalian potassium channel Kv1.2. We focus on the transmembrane movement of the voltage sensor as a key element to the detection of membrane potential and to the control of channel gating. 相似文献
