CLIP (86-100) is amino acids 86 to 100 fragment of class II-associated invariant chain peptide (CLIP). CLIP is a small self-peptide and cleavage product of the invariant chain that resides in the HLA-II antigen binding groove and is believed to play a critical role in the assembly and transport of MHC class II alphabetaIi complexes through its interaction with the class II peptide-binding site.
