receptor ligand activity

Term ID

GO:0048018

Synonyms

receptor agonist activity
receptor ligand activity
signaling molecule
signaling receptor ligand activity
vitamin D receptor activator activity

Definition

The activity of a gene product that interacts with a receptor to effect a change in the activity of the receptor. Ligands may be produced by the same, or different, cell that expresses the receptor. Ligands may diffuse extracellularly from their point of origin to the receiving cell, or remain attached to an adjacent cell surface (e.g. Notch ligands).
