cNPDB: A comprehensive empirical crustacean neuropeptide database

Neuropeptides, key signaling molecules essential for dynamic regulation of biological processes, have been studied via crustacean model systems for more than 40 years. We present cNPDB, the first centralized resource dedicated to this dynamic area of research, promisingly accelerating crustacean neuropeptidome research and offering a blueprint for cross-species translational studies of neuropeptide signaling. cNPDB is comprised of 1364 published neuropeptides from 29 crustacean species, each annotated with corresponding taxonomic information, computed physicochemical properties, spatial localization, and predicted three-dimensional structure. The intuitive web-interface supports keyword and property-based filtering, sequence alignment, property calculation, and links to available mass spectrometry imaging data, streamlining discovery.
