Figure 1. ZNF598 is a translation repressor that sediments with polysomes.

Figure 1

(a) Domain organization of the human ZNF598 protein and its yeast orthologue Hel2 as determined by Interpro. The protein length in amino acids (aa) is indicated. (b) Polysome profiles of empty vector (EV) and ZNF598-OE HEK293 cells. (c) Polysome profiles of parental (CTR) and ZNF598-KO HEK293 cells. (d) Western blot analysis of ZNF598 expression and EIF2S1 phosphorylation (p-EIF2S1) to probe for proteotoxic stress in ZNF598-OE and ZNF598-KO cells and controls. * Indicates a non-specific band recognized by the anti-ZNF598 antibody (GeneTex). Numbers indicate the ratio of ZNF598 expression relative to CTR cells. (e) Western blot analysis with the indicated antibodies of fractions of the ZNF598-OE HEK293 cell lysates after separation over a 10–50% sucrose gradient. The position of 80S ribosomes and polysomes in the gradient is indicated.
