From: High-intensity light disrupts intracellular organelle dynamics via microtubule depolymerization
The molecular mechanism of xanthosomes dispersion caused by high-intensity light illumination in L. crocea. (A) High-intensity light triggered the release of Ca2+ through IP3R calcium ion channels in the ER of xanthophores. (B) Sustained Ca2⁺ release through IP₃R channels led to elevated intracellular Ca2⁺ levels, which subsequently induced microtubule depolymerization. (C) Microtubule depolymerization disrupts centripetal transport along microtubule tracks, leading to xanthosome dispersion.
