Neuropeptides are critical signaling molecules involved in numerous physiological processes, including metabolism, reproduction, development, and behavior. In crustaceans, neuropeptides regulate key biological functions such as molting, feeding, and immune responses. Despite their significance, crustacean neuropeptides remain underrepresented in existing neuropeptide databases.
To address this gap, we introduce The Crustacean Neuropeptide Database (CNPD) – A comprehensive resource for neuropeptide research in crustacean species. CNPD systematically curates experimentally confirmed and predicted neuropeptides from various crustacean species using Peer-reviewed literature, Mass spectrometry-based peptidomics, and Public protein databases
This database provides detailed annotations to support Comparative neurobiology , Functional studies, and Computational peptide discovery
CNPD is a community-driven initiative! We welcome contributions from researchers in peptidomics, neurobiology, and comparative physiology.
