In Figure 2, amino acids 512, 552 and 586 should be listed as caspase cleavage sites, not phosphorylation sites, and should be aspartate residues, not serines.

Caspase cleavage of HTT is reviewed here: http://www.ncbi.nlm.nih.gov/pubmed/21311053

These sites are well established as caspase cleavage sites and are also listed on the Human protein resource database here: http://www.hprd.org/summary?hprd_id=00883&isoform_id=00883_1&isoform_name=Isoform_1
