RNF20 promotes site-specific heterochromatin relaxation in an SNF2H-dependent manner. (A) Schematic for site-specific chromatin relaxation assay. (B) Cells containing an integrated LacO array within a region of heterochromatin were treated ± siRNA toward luciferase (siLuc) or SNF2H (siSNF2H) and transfected with RNF40Myc and either LacR or LacR-RNF20, as indicated. Color scales indicate false-colored lookup table of pixel intensities (8 bit, pixel range = 1–256). (C and D) The nuclear volume of the LacR-signal (array) as a percentage of the overall nuclear volume was plotted for each condition, either as individual data points (C) or a mean of three independent experiments (D). P-values (standard two-tailed Student’s t test) are indicated. Error bars show SD.
