Objective(s):EMAP-like Protein 5 (EML5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. The aim of this study was to investigate the expression profile of EML5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (IE). Materials and Methods:Western blot assays were performed to determine EML5 expression in 36 su...
1. The stiffness (flexural rigidity) of some echinoderm sperm flagella was measured, using a flexible glass microneedle. 2. Values of 0-3-1 -5 x io a i N m were obtained for the stiffness of live flagella which were immobilized with COg-saturated sea water. 3. The immobilized live flagellum was uniform in stiffness along its entire length, except in a particular plane of imposed bending in whic...
Echinoderms attach strongly and temporarily to the substratum by means of specialized organs, the podia or tube feet. The latter consist of a basal extensible cylinder, the stem, which bears an apical flattened disc. The disc repeatedly attaches to and detaches from the substratum through adhesive and de-adhesive secretions. In their activities, echinoderms have to cope with substrata of varyin...
When saturated with ATP, sea cucumber myosin hydrolyzes ATP about 15 times more slowly than rabbit myosin, as expected from the slower contraction time of the muscle. The Arrhenius plots coincide at low temperatures, but only the rabbit plot changes slope at higher temperatures. This unexpected change in slope apparently results from the use of Verona1 buffer. At high substrate concentrations i...
Cathepsin D is an important lysosomal aspartic protease and is transported to the lysosomes in both mannose 6-phosphate dependent and independent manner. The present study reports lysosomal transport and proteolytic characterization of cathepsin D purified from gonads of starfish Asterias Rubens. Activity of the purified enzyme was confirmed by a zymogram assay on hemoglobin. Characterization o...
We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The g...
