Tau interacts with STH but not with Prdx6, and seems to require the C-terminus of STH for interaction. The Western blots are of protein lysate inputs (top and middle panels) and co-IPs (bottom panels) from co-transfections into COS cells. The lysates were normalized for protein content. Standard markers are indicated on the left of each panel, proteins on the right. The primary antibodies used for IP and/or detection are listed below each panel. M = mouse monoclonal, R = rabbit polyclonal. (A) Co-IPs of FLAG-tau and GFP-STH or -Prdx6. (B) Co-IPs of FLAG-tau and GFP-STHQ deletion constructs.
