Centromeres from lower eukaryotes
Introduction Most eukaryotic chromosomes contain a specialized domain — the centromere — that mediates critical mitotic and meiotic functions, including kinetochore nucleation, spindle attachment, and sister chromatid cohesion. These processes ensure faithful chromosome partitioning during cell division. Intense scrutiny of the DNA and proteins that comprise the centromere revealed its fundamen...
متن کاملUniquely Represented Data Structures for Computational Geometry
We present new techniques for the construction of uniquely represented data structures in a RAM, and use them to construct efficient uniquely represented data structures for orthogonal range queries, line intersection tests, point location, and 2-D dynamic convex hull. Uniquely represented data structures represent each logical state with a unique machine state. Such data structures are strongl...
متن کاملComparison of Alternative Splicing Structures in Eukaryotes
Numerous databases of alternative splice forms have been generated over the recent years, which – beside of using heterogenous input data – differ substantially in the definition and in the representation of patterns. Motivated by this, we have developed a novel relative position notation system to univocally describe alternative splicing (AS) events, and a parsing and visualization tool (AStaL...
متن کاملVaults. II. Ribonucleoprotein structures are highly conserved among higher and lower eukaryotes
Vaults are cytoplasmic ribonucleoprotein structures that display a complex morphology reminiscent of the multiple arches which form cathedral vaults, hence their name. Previous studies on rat liver vaults (Kedersha, N. L., and L. H. Rome. 1986. J. Cell Biol. 103:699-709) have established that their composition is unlike that of any known class of RNA-containing particles in that they contain mu...
متن کاملCalcineurin-Crz1 signaling in lower eukaryotes.
Calcium ions are ubiquitous intracellular messengers. An increase in the cytosolic Ca(2+) concentration activates many proteins, including calmodulin and the Ca(2+)/calmodulin-dependent protein phosphatase calcineurin. The phosphatase is conserved from yeast to humans (except in plants), and many target proteins of calcineurin have been identified. The most prominent and best-investigated targe...
