General Information
Term antigen processing and presentation of peptide antigen ID (Ontology) GO:0048002 (Gene Ontology)
Definition The process in which an antigen-presenting cell expresses peptide antigen in association with an MHC protein complex on its cell surface, including proteolysis and transport steps for the peptide antigen both prior to and following assembly with the MHC protein complex. The peptide antigen is typically, but not always, processed from an endogenous or exogenous protein.[ ISBN:0781735149 PubMed:15771591 ]
Also Known As "antigen presentation, peptide antigen" ; "peptide antigen processing and presentation"
