Synaptotagmins are a large gene family in animals that have been extensively characterized due to their role as calcium sensors to regulate synaptic vesicle exocytosis and endocytosis in neurons. and dense core vesicle exocytosis for hormone secretion from neuroendocrine cells. Thought to be exclusive to animals. synaptotagmins have recently been characterized in Arabidopsis thaliana. https://parisnaturalfoodes.shop/product-category/seabuckthorn-berry-lotion/
