Class: MolecularEntity

A gene, gene product, small molecule or macromolecule (including protein complex)

URI: biolink:MolecularEntity








Uses Mixins

  • mixin: ThingWithTaxon - A mixin that can be used on any entity with a taxon
  • mixin: PhysicalEntity - An entity that has physical properties such as mass, volume, or charge


  • ChemicalSubstance - May be a chemical entity or a formulation with a chemical entity as active ingredient, or a complex material with multiple chemical entities as part
  • GeneFamily - any grouping of multiple genes or gene products related by common descent
  • GenomicEntity - an entity that can either be directly located on a genome (gene, transcript, exon, regulatory region) or is encoded in a genome (protein)

Referenced by class


Inherited from gene product:

  • id REQ
    • Description: A unique identifier for a thing. Must be either a CURIE shorthand for a URI or a complete URI
    • range: String
    • in subsets: (translator_minimal)
  • name REQ
    • Description: A human-readable name for a thing
    • range: LabelType
    • in subsets: (translator_minimal)

Inherited from named thing:

  • category 1..*
    • Description: Name of the high level ontology class in which this entity is categorized. Corresponds to the label for the biolink entity type class.
  • In a neo4j database this MAY correspond to the neo4j label tag.
  • In an RDF database it should be a biolink model class URI. This field is multi-valued. It should include values for ancestors of the biolink class; for example, a protein such as Shh would have category values bl:Protein, bl:GeneProduct, bl:MolecularEntity, … In an RDF database, nodes will typically have an rdf:type triples. This can be to the most specific biolink class, or potentially to a class more specific than something in biolink. For example, a sequence feature f may have a rdf:type assertion to a SO class such as TF_binding_site, which is more specific than anything in biolink. Here we would have categories {bl:GenomicEntity, bl:MolecularEntity, bl:NamedThing}

Inherited from thing with taxon:

  • in taxon 0..*
    • Description: connects a thing to a class representing a taxon
    • range: OrganismTaxon
    • in subsets: (translator_minimal)
