Scientists identify novel lysosome fission factor

Lysosomes are centers for degradation, recycling, and signaling of cellular materials that are crucial for maintaining cellular homeostasis, development, and aging. To meet various physiological demands, lysosomes continuously remodel their shape and function through fusion and fission processes. While lysosome fusion process has been extensively studied, little is known about lysosome fission. The molecules responsible for lysosomal membrane fission have not been identified.
