Supplementary Material

The supplemental figures included with this manuscript are biochemical analyses that demonstrate that KR-TCRα is modified on an internal, non-lysine residue. In addition, also included is a figure demonstrating that an endogenous, human protein is also ubiquitinated and degraded by the proteasome.
