The Journal of Membrane Biology publishes high‑quality research that advances the understanding of the biophysical, biochemical, and functional properties of biological membranes. We welcome studies across all domains of life and encourage work that deepens insight into membrane structure, signaling, transport, communication, and energy‑related processes at molecular, cellular, and physiological levels. The journal covers membrane biology in human health and disease, as well as in animal, plant, fungal, bacterial and viral systems, including comparative, evolutionary, and mechanistic investigations. We also welcome research on synthetic or bioengineered biomembranes, provided that the systems are biologically derived, biologically inspired, or directly relevant to membrane biology. Computational and theoretical membrane biology (MD simulations, coarse-grained modeling, machine learning, which is relevant to any of the below sections, is also welcome. While we welcome connections to clinical studies, submissions that are primarily clinical in nature or that fail to make connections to the basic science issues of membrane structure, chemistry and function, are not appropriate for the journal. In a similar way, studies that are primarily descriptive and narratives of assays in a clinical or population study are best published in other journals. If you are not certain, please write to us to inquire if your study is a good fit for the journal. Core areas of interest 1.
