antigen processing and presentation of exogenous protein antigen via MHC class Ib, TAP-independent

Term ID

GO:0002482

Synonyms

• exogenous peptide antigen processing and presentation via MHC class Ib, TAP-independent
• TAP-independent antigen processing and presentation of exogenous peptide antigen via MHC class Ib
• TAP-independent exogenous peptide antigen processing and presentation via MHC class Ib

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 Ib protein complex following intracellular transport via a pathway not requiring TAP (transporter associated with antigen processing). 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. 15928678
