The short filaments extending from the cytoplasmic face of nuclear pore complexes are thought to contain docking sites for nuclear import substrates. One component of these filaments is the large O-linked glycoprotein CAN/Nup214. Immunoprecipitation studies carried out under nondenaturing conditions, and using a variety of antibodies, reveal a novel(More)
Nup153 is a large O-linked glycoprotein that is a component of the basket-like structure that forms the nucleoplasmic face of nuclear pore complexes (NPCs). The Nup153 molecule has a tripartite structure consisting of N- and C-terminal domains flanking a central zinc finger domain. All of the targeting and assembly information contained within Nup153 is(More)
This paper presents an approach to describe business process in production systems using workflow concepts. In this sense, we define an extension of the UML Activity Diagram called Workflow Activity Diagram (WAD) which applies the C-WF model concepts. The C-Wf model represents the structural and functional enterprise objects involved in the business(More)
The membrane-spanning glycoprotein gp210 is a major component of the nuclear pore complex. This nucleoporin contains a large cisternal N-terminal domain, a short C-terminal cytoplasmic tail, and a single transmembrane segment. We show here that dimers of native gp210 can be isolated from cell extracts by immunoprecipitation, and from purified rat liver(More)
Overlapping clones which contain the complete gene encoding the human lymphocyte IgE receptor (MW:45kd; identical with CD23), were isolated from human genomic lambda-libraries. The gene spans approximately 13kb and comprises 11 exons. The 5'-end of the mRNA was mapped by primer extension and S1-mapping, revealing two initiation sites for transcription. Two(More)
This work presents an object-oriented approach to model business processes in production systems using workflow concepts. We define an object reference model called C-Wf that represents the structural and functional enterprise elements involved in the business processes, such as enterprise activities, human resources, machines, etc. Through the C-Wf(More)
This paper presents an approach to describe business process in production systems using workflow concepts. This work presents an approach to model workflow applications based on the C-Wf model and UML (Unified Modeling Language) Activity Diagrams. The C-Wf model represents the structural and functional enterprise objects involved in the business processes,(More)
E-Learning is a process in which electronic medium is used to access the defined set of applications and processes. In e-Learning environment, automatic classification of learning materials is essential due to lack of common vocabulary of the knowledge area in some context. Ontology has the potential to play an important role in representing an area of(More)
