Experimental details: RNA immunoprecipitation (RIP) western of p23 was performed on K562 cells. Antigen-antibody complexes were formed by incubating approximately 500 µg whole cell lysate with 5 µg of p23 monoclonal antibody (Product # MA3-414) rotating 60 min at RT. The immune complexes were captured on 625 µg of anti-mouse coated Dynabeads (Product # 11202D), washed extensively, and eluted with NuPAGE™ LDS Sample Buffer (Product # NP0007). Samples were resolved onto NuPAGE™ 4-12% Bis-Tris gel (Product # NP0335BOX). Lanes 1 and 3 are input and lanes 2 and 4 are IP. Proteins were transferred to PVDF membrane (Product # IB23001). Membrane was blocked in 5% milk. Target was detected using a p23 monoclonal antibody (Product # MA3-414) at a dilution of 1:2000, followed by a 1:4000 dilution of secondary antibody. Chemiluminescent detection was performed using ECL Western Blotting Substrate (Product # 32106). Data courtesy of the Yeo lab as part of the ENCODE project (www.encodeproject.org).

Experimental details: FIGURE 4. Caspase-1 exhibits greater promiscuity toward natural substrates than caspases-3 or -7. A , processing of substrate proteins in Jurkat cell-free extracts after addition of the indicated amounts of recombinant caspase ( Casp )-1, -3, and -7 followed by incubation for 2 h at 37 degC. Recombinant caspases were active site titrated (see supplemental Fig. S1 ) as described under ""Experimental Procedures."" Recombinant IL-1beta (10 ng per reaction) was added to cell-free extracts as a positive control for caspase-1 activity. Substrate proteolysis was detected by SDS-PAGE followed by immunoblotting. B , caspase-1-mediated processing of the purified recombinant proteins over the indicated concentration ( Conc. ) range. The indicated proteins were incubated with recombinant active caspase-1 for 2 h at 37 degC. C , caspase-3-mediated processing of the purified recombinant proteins over the indicated concentration range. The indicated proteins were incubated with recombinant active caspase-3 for 2 h at 37 degC. Results are representative of at least three independent experiments.

(a) Undifferentiated N2a cells were stained with the Ac88 clone anti-hsp90 (red), which does not recognize the chaperone unless it is free or denatured. FKBP52 was used as marker of the perinuclear ring (green).
