Centromere protein-F (CENP-F) is mammalian kinetochore protein that was recently identified by an autoimmune serum (Rattner, J. B., A. Rao, M. J. Fritzler, D. W. Valencia, and T. J. Yen. Cell Motil. Cytoskeleton. 26:214-226). We report here the human cDNA sequence of CENP-F, along with its expression and localization patterns at different stages of the HeLa(More)
OBJECTIVE Human autoantibodies reacting with protein components of the microtubule organizing center of the cell, the centrosome, are rare and have not been extensively studied. We therefore investigated the number, type, and frequency of autoantibodies reactive with centrosomal proteins in a cohort of human sera. METHODS To establish the type of(More)
Autoantibodies directed to a variety of cellular antigens and organelles are a feature of autoimmune diseases. They have proven useful in a clinical setting to establish diagnosis, estimate prognosis, follow disease progression, alter therapy, and initiate new investigations. Cellular and molecular biologists have used autoantibodies as probes to identify(More)
We present a new approach to the simulation and analysis of immune system (IS) behavior. The simulations that can be performed with our software package called SIMMUNE are based on immunological data that describe the behavior of IS agents (cells, molecules) and the IS's challengers (bacteria, viruses) on a microscopical (i.e. agent-agent interaction) scale(More)
The centrosome found in animal cells is a complex and dynamic organelle that functions as the major microtubule organizing center. Structural studies over the past several decades have defined the primary structural features of the centrosome but recent studies are now beginning to reveal structural detail previously unknown. Concurrent with these studies(More)
The behaviour of the centrosome immediately following cell division in tissue culture cells has been investigated. We find that following karyokinesis, but preceding cytokinesis, sister centrosomes relocate from the spindle poles to a position adjacent to the intercellular bridge. This repositioning is accompanied by the appearance of a microtubule bundle(More)
A wireless network solution is generally implemented when the bounds of walls of buildings and the constraints of wires need to be broken. Wireless technologies provide the potential for freedom of mobility which is undoubtedly a convenience for organisations in today's market. The security of a wireless network is crucial for data integrity, especially(More)
We have identified a putative 35-kilodalton protein that colocalizes with microtubules and displays a unique spatial and temporal distribution during the cell cycle of HeLa cells. This protein has been given the designation MSA-35. MSA-35 first appears in association with microtubules and centrosomes of interphase cells exhibiting centrosome separation as a(More)
