Immunodetection of Spectrin-like Proteins in Yeasts

Popis výsledku v původním jazyce

Spectrin, a component of the membrane skeleton in erythrocytes and other animal cells, has also been identified in plant and fungal cells. However, its postulated role, i.e., the maintenance of shape and elasticity of the plasma membrane, is probably notexerted in walled cells. To study spectrin in these cells, we chose yeasts because of a high morphological variability of their life cycle. The localization of spectrin in the cells and protoplasts of Saccharomyces cerevisiae and Schizosaccharomyces japonicus var. versatilis was detected by Western blotting, indirect immunofluorescence and immunogold electron microscopy techniques with the use of anti-chicken and anti-human erythrocyte spectrin antibodies. A 220/240 kDa protein band and some bands of lower molecular weights were detected in cell and protoplast extracts of both yeast strains. Spectrin-like proteins were revealed by fluorescence microscopy at cell surfaces and in vacuolar membranes. Immunogold-labelling showed spectrin-l
