Experimental details: Immunoprecipitation of beta-actin was performed using NIH/3T3 cells. Antigen-antibody complexes were formed by incubating 500 µg of NIH/3T3 whole cell lysates with 2 µg of a beta-actin monoclonal antibody (Product # MA1-140) overnight on a rocking platform at 4°C. The immune complexes were captured on 100 µL Protein A/G Agarose (Product # 20421), washed extensively, and eluted with 5X Lane Marker Reducing Sample Buffer (Product # 39000). The IP eluate (right lane) and 15 µg of NIH/3T3 lysate (left lane) were resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween for at least 1 hour. The membrane was probed with a beta-actin monoclonal antibody (Product # MA1-140) at a dilution of 1:8000 overnight rotating at 4°C, washed in TBST, and probed with n HRP-conjugated anti-mouse light chain secondary antibody a dilution of 1:40,000 for at least 1 hour.

(A) A549 cells were treated with siRNAs against three protein phosphatases (PP2Ac, PP4c, and PP5c) followed by UV treatment at 40 J/m 2 with a 2 h recovery. Analysis of cytoplasmic extracts reveals that PP2A is required to dephosphorylate cytoplasmic pATR (S428). (B) siRNA knockdown of PP2Ac in A549 cells was followed by UV treatment at 40 J/m 2 with a 2 h recovery. pATR (S428) levels are increased in cytoplasm with PP2Ac knockdown while the phosphorylation status of ATR in the nucleus remains unchanged.

A) Different cell lines were analyzed for ACE2 expression by immunoblotting, with beta-actin as loading control. B) Same as in (A) but with the stably ACE2 transduced U87 cells, tested at an early (# 1) or late (# 32) passage of the cells. The transduced U87 cells stably express ACE2 at a very high level as compared to endogenous ACE2 in the Vero E6 cells. The same immunoblot is used for panel A and B, but with a longer exposure time for panel A in order to visualize the faint band in the Calu-3 sample. C) Comparative qPCR analysis of TMPRSS2 mRNA levels in different cells. Graph shows individual copy numbers/mul of 3 technical replicates (n = 3) as calculated from a TMPRSS2 standard. The TMPRSS2 level in Vero E6 cells was below detection limit. D) Different cell lines were analyzed for Cathepsin L (CTSL; left) and Cathepsin B (CTSB; right) expression by immunoblotting, with clathrin as loading control. For CTSL, different species are detected (indicated by the bracket): Pro-CTSL (41 kDa), glycosylated mature CTSL (31 kDa) and non-glycosylated mature CTSL (25 kDa), whereas only the Pro-CTSB form (42 kDa) is visualized. M: molecular marker in kDa, UD: undetectable. Fig. 1
