Determinants of Peroxisome Membrane Dynamics

Cells rely on dynamic organelles to perform essential functions, and peroxisomes are no exception. These small organelles are involved in lipid metabolism and reactive oxygen species regulation. Their membranes undergo significant shape changes during proliferation. Despite this, the mechanisms controlling peroxisome membrane dynamics remain poorly understood. Prior studies have identified peroxisome plasticity as critical for cell health, but the specific factors influencing membrane dynamics are unclear. The role of peroxins like PEX11 has been noted in some models, but their exact contributions remain debated. Research has shown that membrane composition and biophysical properties influence organelle behavior in other systems, suggesting a similar mechanism may apply to peroxisomes. However, no prior work has resolved how these properties interact with peroxisomal proteins to regulate dynamics. This uncertainty drives the need to explore the molecular and physical determinants of peroxisome membrane behavior.

The goal of this review is to explore the factors that regulate peroxisome membrane dynamics. It aims to clarify how membrane composition and protein interactions influence peroxisome shape changes. The authors seek to integrate findings from multiple disciplines to provide a comprehensive overview. They focus on the role of PEX11 in membrane elongation and division. The study also aims to highlight gaps in current knowledge and identify areas for future research. By synthesizing data from various model systems, the authors hope to reveal common mechanisms. They aim to clarify how peroxisome dynamics affect organelle biogenesis and function. This review proposes that understanding membrane dynamics could lead to insights into peroxisome-related diseases.
