General Information
Term antigen processing and presentation of exogenous peptide antigen via MHC class I ID (Ontology) GO:0042590 (Gene Ontology)
Definition The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class I protein complex. The peptide antigen is typically, but not always, processed from a whole protein. Class I here refers to classical class I molecules.[ ISBN:0781735149 PubMed:15771591 ]
Also Known As "antigen presentation, exogenous antigen via major histocompatibility complex class I" ; "antigen presentation, exogenous antigen via MHC class I" ; "exogenous peptide antigen processing and presentation via MHC class I"
