Term Information

Accession: GO:0003823
Name: antigen binding
Ontology: molecular_function
Synonyms: antibody activity, B cell receptor activity, MHC activity, major histocompatibility complex activity, major histocompatibility complex antigen display activity, opsonin activity
Alternate IDs: None
Definition: Binding to an antigen, any substance which is capable of inducing a specific immune response and of reacting with the products of that response, the specific antibody or specifically sensitized T-lymphocytes, or both. Binding may counteract the biological activity of the antigen. Antigen binding by an MHC protein complex allows the antigen to be displayed to a T cell or NK cell.
