Fig. 4. CMTr2 localizes to distinct sites of transcription and has a dedicated set of targets.

a–j Representative images of polytene chromosomes from salivary glands from three replicates expressing CMTr1::HA (a–e) or CMTr2::FLAG (f–j) stained with anti-Pol II (magenta, d, i), anti-HA (green, c, h), and DNA (DAPI, blue, b, g), or merged (white, a, e, f, j). Arrowheads indicate the absence of CMTr2. Scale bars in f are 10 µm and in g are 2 µm. k Functional classification of CMTr2 CLIP targets.
