Handout IG2-2 Class I MHC-Peptide Interactions Place the steps of the antigen-processing pathway for endogenous antigen in the correct order Alpha chain of class I MHC binds peptide. Endogenous antigen within cytosol is degraded by proteasome. Peptides are transported into endoplasmic reticulum by TAP Alpha chain of class I MHC binds β2-microglobulin. Peptide-class I MHC is transported to Golgj complex and then to cell surface. Class I MHC peptide binds to CD8+T cell.

The transporter in antigen processing genes encode subunits of a heterodimer pump that transports peptides from the cytosol into the endoplasmic reticulum, where they can associate with newly translated Class la chains O B-2 microglobulin. Proteosomes. Immunoglobulin molecules. Class Il a and B chains. Question 20 5 pts Soluble proteins are examples of: Bone marrow dependent antigens. Bone marrow independent antigens., Thymus dependent antigens. Thymus independent antigens. Good food. The features of bound peptide fragments isolated from different class molecules...

Which of the following statements about the role of the COPI or COPII proteins in vesicular transport is CORRECT? They pinch and fuse the membrane to allow separation of the vesicle from the rest of the membrane of the donor compartment. They increase the curvature of the membrane and form the vesicle from the donor compartment. They bind to the membrane of the target organelle/compartment to ensure delivery specificity. They regulate the fusion of the vesicle membrane with its target...
