AI Article Synopsis

  • Centrins are calcium-binding proteins part of the CaM superfamily, specifically from the ciliate Euplotes Octocarinatus.
  • The centrin was expressed in E. coli, purified, and crystallized using the hanging-drop method.
  • The resulting rod-like crystals diffracted to 2.0 angstroms and belong to the space group P2(1)2(1)2(1) with specific unit-cell parameters.

Article Abstract

Centrins are four-EF-hand Ca(2+)-binding proteins, which belong to the CaM super family. The centrin from ciliate Euplotes Octocarinatus has been expressed in Escherichia coli, purified and crystallized using the hanging-drop method. Rod-like crystals were grown and diffracted to 2.0 angstroms. The crystals belong to space group P2(1)2(1)2(1) and the unit-cell parameters are a=34.442 angstroms, b=48.954 angstroms, c=72.583 angstroms.

is a unicellular ciliate capable of contracting to a quarter of its body length in less than five milliseconds. When measured as fractional shortening, this is an order of magnitude faster than motion powered by actomyosin. Myonemes, which are protein networks found near the cortex of many protists, are believed to power contraction.

Article Synopsis
  • * The mechanism behind this shape-shifting is unclear but involves a unique system of actin and myosin, differing from other ciliates that use calcium-dependent methods.
  • * Two types of cytoskeletons, myoneme and microtubule, exist in Lacrymaria, with a newly discovered giant protein facilitating coordination between them, enabling effective neck-body independence during movement.

Immunohistochemical identification of epithelial cell types in the isthmus of bovine oviduct: Comparison with the ampulla.

Laboratory of Reproductive Physiology, Graduate School of Environmental and Life Science, Okayama University, Okayama 700-8530, Japan.

The oviductal epithelium consists of ciliated and non-ciliated cells, and their numbers vary depending on the segment of the oviduct and stage of the estrous cycle. Compared with the ampulla, fewer cyclic changes in the number of the two types of cells occur in the isthmus. Recently, we have reported that the epithelium in the ampullary oviduct is composed of many types of cells during different translational/transcriptional states, and their numbers change during the estrous cycle.

Cellular components are non-randomly arranged with respect to the shape and polarity of the whole cell. Patterning within cells can extend down to the level of individual proteins and mRNA. But how much of the proteome is actually localized with respect to cell polarity axes? Proteomics combined with cellular fractionation has shown that most proteins localize to one or more organelles but does not tell us how many proteins have a polarized localization with respect to the large-scale polarity axes of the intact cell.

Nonspecific binding of common anti-CFTR antibodies in ciliated cells of human airway epithelium.

There is evidence that the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel is highly expressed at the apical pole of ciliated cells in human bronchial epithelium (HBE), however recent studies have detected little CFTR mRNA in those cells. To understand this discrepancy we immunostained well differentiated primary HBE cells using CFTR antibodies. We confirmed apical immunofluorescence in ciliated cells and quantified the covariance of the fluorescence signals and that of an antibody against the ciliary marker centrin-2 using image cross-correlation spectroscopy (ICCS).
