An 100-kDa Ca2+-sensitive actin-fragmenting protein from unfertilized sea urchin egg
TL;DR: An actin-modulating protein was purified from unfertilized eggs of sea urchin, Hemicentrotus pulcherrimus, by means of DNase I affinity and DEAE-cellulose column chromatographies and revealed that one 100-kDa protein molecule binds two or three actin monomers in the presence of Ca2+, but such binding was not observed in the absence ofCa2+.

The Mitotic Apparatus with Unusually Many Microtubules from Sea Urchin Eggs Treated by Hexyleneglycol. (microtubule/mitotic apparatus/granular material/sea urchin)
TL;DR: By treating sea urchin eggs at prometaphase and metaphase with hexyleneglycol, the mitotic apparatus was found to become remarkably decorated with unusually many astral microtubules which were conspicuously uniform in length.

Binding of kinesin to stress fibers in fibroblasts under condition of microtubule depolymerization
TL;DR: Observations strongly suggest that kinesin has affinity not only to microtubules but also to stress fibers in culture cells.
