Cytoplasmic dynein-mediated intracellular transport needs the multi-component dynactin complex for cargo binding and motor activation.

In filamentous fungi, microtubules are important for polar growth and morphological maintenance serve as rails intracellular trafficking. The molecular mechanisms associated with have been analyzed. However, little is known about when where tubulin, a component of microtubules, biosynthesized in multinuclear multicellular fungi. this study, we visualized based on the enhanced green fluorescence protein (EGFP)-labeled α-tubulin β-tubulin mRNA tagged by EGFP-mediated MS2 system living yellow Koji mold Aspergillus oryzae cells order to understand spatiotemporal production mechanism tubulin. We found that btuA, encoding β-tubulin, localized at dot-like structures through apical, middle basal regions hyphal cells. addition, some btuA dots showed microtubule-dependent motor protein-like dynamics Furthermore, it was were decreased cytoplasm just before mitosis but increased immediately after mitosis, followed gradual decrease. summary, localization abundance spatiotemporally regulated A.
