Biological membranes composed of lipids and proteins are central for the function all cells individual components, such as proteins, that readily studied by a range structural approaches, including x-ray crystallography cryo-electron microscopy. However, study complex molecular mixtures within biological membrane structure dynamics requires techniques can nanometer thick bilayers in an aqueous environment at ambient temperature pressure. Neutron methods, scattering spectroscopic useful since they measure while also being able to penetrate sample holders cuvettes. The small angle neutron reflectometry, detect caused difference contrast (scattering length) between different components or proteins.

Since the rise of cellular life, transmembrane proteins (TMPs) have been crucial to various processes through their central role as gates and gatekeepers. Despite importance, experimental high-resolution structures for TMPs remain underrepresented due challenges. Given its performance leap, structure predictions begun close gap. However, identifying membrane regions topology in three-dimensional files on a large scale still requires additional silico predictions. Here, we introduce TMVisDB sieve millions predicted TMPs.
