We found that depletion of extracellular mutant 29 (Ecm29), an adaptor protein that binds to a subset of 26S proteasomes (Ecm proteasomes), increased the abundance of TLR3 in human embryonic kidney-293 and HeLa cells.

20S proteasome and most 19S subunits were however not changed but Ecm29, a protein known to stabilize the interactions between the 20S and its activators, was decreased in the isolated ethanol proteasome fractions.
