High molecular weight protein detected in higher plant cells by antibodies against dynein is associated with vesicular organelles including Golgi apparatus

High molecular weight protein detected in higher plant cells by antibodies against dynein is... The cytoplasmic dynein is a multisubunit complex driving organelles along microtubules to their minus-end. We used antibodies against two functional domains (motor and microtubule-binding) of one of principal components of the complex—dynein heavy chain of slime mould Dictyostelium discoideum—to test root meristem cells of wheat Triticum aestivum. The antibodies reacted with a high molecular weight protein (>500 kDa) in the total cell extract and the band recognized by the antibodies in plant extracts had a lower electrophoretic mobility than the high molecular weight band of mammalian dynein. Antibodies coupled to protein A-Sepharose precipitated the high molecular weight protein from the purified cell extracts. Immunocytochemical analysis demonstrated that the antigen recognized by antibodies against dynein heavy chains is associated with the vesicles whose localization depends on the cell cycle stage. The antigen-positive vesicles were localized to the perinuclear region in interphase and early prophase, to the spindle periphery and to spindle pole region during mitosis, and to the interzonal region in the period of fragmoplast and cell plate formation. Some antigen-positive vesicles also reacted with antibodies against Golgi protein markers. The obtained data indicate that higher plant cells contain a high molecular weight protein interacting with antibodies against the motor and microtubules-binding domains of Dictyostelium dynein heavy chain. The revealed antigen was associated with the vesicular structures in the cytoplasm including the Golgi apparatus. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals
