- antigen processing and presentation via MHC class Ib
The process in which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC class Ib protein complex. Class Ib here refers to non-classical class I molecules, such as those of the CD1 or HLA-E gene families.
- MHC class Ib receptor activity
Combining with an MHC class Ib protein complex and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. Class Ib here refers to non-classical class I molecules, such as those of the CD1 or HLA-E gene families.
- MHC class Ib protein complex
A transmembrane protein complex composed of a MHC class Ib alpha chain and, in most cases, an invariant beta2-microglobin chain, and with or without a bound peptide or lipid antigen. Class Ib here refers to non-classical class I molecules, such as those of the CD1 or HLA-E gene families.
- miRNA metabolic process
The chemical reactions and pathways involving miRNA, microRNA, a class of single-stranded RNA molecules of about 21-23 nucleotides in length, which regulates gene expression.
- antigen processing and presentation of endogenous peptide antigen via MHC class Ib
The process in which an antigen-presenting cell expresses a peptide antigen of endogenous origin on its cell surface in association with an MHC class Ib protein complex. The peptide is typically a fragment of a larger endogenous 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.
- antigen processing and presentation of exogenous peptide antigen via MHC class Ib
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.
- miRNA catabolic process
The chemical reactions and pathways resulting in the breakdown of miRNA, microRNA, a class of single-stranded RNA molecules of about 21-23 nucleotides in length, which regulates gene expression.
- MHC class I receptor activity
Combining with an MHC class I protein complex to initiate a change in cellular activity. Class I here refers to classical class I molecules.
