Figure 2: ERp57 was identified as an Hsp70-independent PGRN- and ND7-binding molecule.

(A) The scheme of the method used to identify potential molecules involved in PGRN- and ND7-mediated regulation of GD in Hsp70-independent manner. Immunoprecipitation was performed with His antibody from His-tagged PGRN and His-tagged ND7 treated Hsp70 KO mouse lung epithelium cells, followed by mass spectrometry. PBS treatment was used as a control. (B) Summary of the mass spectrometry hits that specifically bound to both PGRN and ND7.
