Peptide loading complex information


PLC side view

The peptide-loading complex (PLC) is a short-lived, multisubunit membrane protein complex that is located in the endoplasmic reticulum (ER). It orchestrates peptide translocation and selection by major histocompatibility complex class I (MHC-I) molecules. Stable peptide-MHC I complexes are released to the cell surface to promote T-cell response against malignant or infected cells. In turn, T-cells recognize the activated peptides, which could be immunogenic or non-immunogenic.
