name: antigen processing and presentation of exogenous peptide antigen via MHC class Ib
namespace: biological_process
type: go
obsolete: False

Description: 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 Ib protein complex. The peptide is typically a fragment of a larger exogenous protein which has been degraded within the cell. Class Ib here refers to non-classical class I molecules, such as those of the HLA-E gene family.
