Dnm1p/Vps1p-like protein (DVLP) is a mammalian member of the dynamin GTPase family, which is classified into subfamilies on the basis of the structural similarity. Mammalian dynamins constitute the dynamin subfamily. DVLP belongs to the Vps1 subfamily, which also includes yeast Vps1p and Dnm1p. Typical structural features that discriminate between members(More)
Clathrin adaptor protein (AP) complexes are heterotetramers composed of two large, one medium, and one small subunits. By exploiting the yeast three-hybrid system, we have found that an interaction between the two large subunits of the AP-1 complex, gamma-adaptin and beta1-adaptin, is markedly enhanced in the presence of the small subunit, sigma1.(More)
Dynamins are a family of approximately 100-kDa GTPases that are thought to play a pivotal role in the formation of endocytic coated vesicles. There are three dynamin genes in mammals: dynamin I is neuron-specific, dynamin II shows ubiquitous expression, and dynamin III is expressed in testis, brain, and lung. However, most studies on the functions of(More)
Most information retrieval systems, including Web search engines, use similarity ranking algorithms based on a vector space model to find relevant information in response to a user's request. However, the retrieved information is frequently irrelevant, because most of the current information systems employ index terms or other techniques that are variants(More)
The DBMS performance might change by allocating resources and by performing a specific kind of workload. Database administrators should be able to identify relative resources that can change DBMS performance in order to effectively manage database systems. This paper aims to identify the relative resources that can affect the DBMS performance depending on(More)
The rapid growth of on-line information including multimedia contents during the last decade caused a major problem for Web users-there is too much information available, most of it poorly organized and hard to find. To help a user to find proper information, web news search functions are devised and developed. Although those search engines provide some(More)
Most traditional Information Retrieval (IR) systems, including web search engines, operationalize "relevant" as the word frequency in a document of a set of keywords. Because of this limitation, traditional IR systems frequently retrieve irrelevant documents in response to a user’s request. In this paper, we propose a new criterion, "generality," that(More)
The primary goal of this project is to design, develop, deploy, and test methodologies for exploiting semantic aspects of the data. Toward this end, we have developed an information system based on ontologies (collections of key concepts and terms along with their interrelationships) to provide intelligent information selection. The main capabilities of the(More)
