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 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...
متن کاملAmino acid transporters of lower eukaryotes: regulation, structure and topogenesis.
Lower eukaryotes such as the yeast Saccharomyces cerevisiae and the filamentous fungus Aspergillus nidulans possess a multiplicity of amino acid transporters or permeases which exhibit different properties with respect to substrate affinity, specificity, capacity and regulation. Regulation of amino acid uptake in response to physiological conditions of growth is achieved principally by a dual m...
متن کاملLamin A, lamin B, and lamin B receptor analogues in yeast
Previous studies have shown that turkey erythrocyte lamin B is anchored to the nuclear envelope via a 58-kD integral membrane protein termed p58 or lamin B receptor (Worman H. J., J. Yuan, G. Blobel, and S. D. Georgatos. 1988. Proc. Natl. Acad. Sci. USA. 85:8531-8534). We now identify a p58 analogue in the yeast Saccharomyces cerevisiae. Turkey erythrocyte lamin B binds to yeast urea-extracted ...
متن کاملA polymer model for large-scale chromatin organization in lower eukaryotes.
A quantitative model of large-scale chromatin organization was applied to nuclei of fission yeast Schizosaccharomyces pombe (meiotic prophase and G2 phase), budding yeast Saccharomyces cerevisiae (young and senescent cells), Drosophila (embryonic cycles 10 and 14, and polytene tissues) and Caenorhabditis elegans (G1 phase). The model is based on the coil-like behavior of chromosomal fibers and ...
