Fig. 4.
Shortened Ahi1 domain in Tmem138b/b photoreceptor CC. Ahi1, Ac-tub, and Rp1 triple labeling for all images. Red, green, and turquoise channels represent Ahi1, Ac-tub, and Rp1, respectively. (A and B) P5 sections. Arrows point to Ahi1 staining, while brackets indicate gaps between Ahi1 and Rp1 staining. (C and D) P8 sections. (E and F) P14 sections. (G) Quantification of Ahi1 domain length, gap length between Ahi1 and Rp1, and Ahi1 domain length plus gap length. The total domain length of “Ahi1 + gap” is roughly equal between wild type and the mutants, suggesting that the gap of the mutant distal CC is a missing part of the Ahi1 domain; ns, no significance.
