Immunoblotting was performed as previously described (13 (link)). The primary antibodies used were: (i) anti-TEG-1 (N-terminal) antibodies at 1:1000 (13 (link)); (ii) anti-VIG-1 antibodies at 1:30 000; (iii) anti-ALG-1 antibodies (Thermo Scientific) at 1:2500; (iv) anti-AGO2 antibodies (Cell Signaling) at 1:1000; (v) anti-GFP antibodies (Rockland) at 1:2000; (vi) anti-SERBP1 antibodies (anti-PAI-RBP1, Abnova) at 1:1000; (vii) anti-actin antibodies (Sigma) at 1:1000; (viii) rabbit anti-ubiquitin antibodies (Sigma) at 1:100 and (ix) anti-paramyosin antibodies (MH16, hybridoma cell line from Developmental Studies Hybridoma Bank, University of Iowa) tissue culture supernatant. Immunoblots were developed with SuperSignal WestPico substrate (Thermo Scientific) or Amersham ECL Select Western Blotting Detection Reagent (GE Healthcare). Blots were exposed to Kodak BioMax MR film.
