Neurotransmitterid

Neurotransmitterid is a proposed standardized identifier system intended to catalog neurotransmitters, neuromodulators, and related signaling molecules across biological databases and research workflows. It aims to bridge chemical identity with signaling function by linking a molecule to its synthesis, release, receptors, and transport mechanisms.

The system would assign a unique code to each molecule, using a hierarchical structure that encodes chemical class, primary identity, and functional context. Codes are designed to be mapped to established resources such as PubChem, ChEBI, and KEGG, and to accommodate synonyms and cross-references. The goal is for identifiers to be stable across database updates and to support integration with multiple data schemas and ontologies used in neuroscience research.

In practice, Neurotransmitterid would be used to annotate molecules in experimental datasets, electronic lab notebooks, and literature databases. It would enable queries that link related entities such as precursors, metabolites, synthesis enzymes, transporters, and receptors, and would be capable of handling a broad range of signaling molecules, including classical neurotransmitters, neuromodulators, neuropeptides, and certain gaseous messengers.

Adoption faces several challenges. Delineating what constitutes a distinct signaling entity can be contentious, particularly for context-dependent roles and for molecules with rapid temporal dynamics. Governance and versioning are required to maintain consistency, and alignment with existing ontologies and databases is essential to avoid fragmentation. Nevertheless, proponents argue that Neurotransmitterid could improve data interoperability, enable more robust meta-analyses, and facilitate cross-species comparisons in neuroscience research. The concept remains largely developmental and subject to community consensus.
