Figure 9. XCPE1 and XCPE2-containing cellular promoters show the same GTF requirements as HBV X gene promoter.

(A) Western blot analyses of depleted NEs. HeLa NE was immunodepleted as indicated and the levels of target factors as well as other GTFs were examined by western blotting. (B) In vitro transcription assays of the immunodepleted NEs. Transcription activities for the XCPE2-containing promoters (ENST268533, NM_16114, and NM_32267), an XCPE1-containing promoter (NM_024811), and the X gene Start site 2 minimal promoter were examined. Arrows show the transcripts starting at the positions expected to be driven by XCPE2 or XCPE1.
