Trafficking of nonameric complex in the endocytic pathway

Locations in the PathwayBrowser

The internalized nonameric complex passes through the endocytic pathway and finally reach the acidic late endosomal/lysosomal compartments, where the Ii component is progressively degraded by proteases. Proteolysis of Ii occurs through sequential cleavages from the lumenal (C-terminal) side, generating cleavage products of approximately 22 kDa (lip22) and 10 kDa (lip10), finally leaving only CLIP bound within the peptide binding groove of MHC II (Landsverk et al. 2009).
