Gene structure of anti-CNG1. Top, schematic illustration of the nucleotide complementarity of anti-CNG1 to sense CNGα1. Black bar, sense CNGα1; gray bar, region of anti-CNG1 complementary to sense CNGα1; hatched bar, region of anti-CNG1 lacking complementarity to sense CNGα1. P1, the region in which the CNGα1-specific riboprobe for in situ hybridization (Figures 5 and 6) was derived; P2, the region in which anti-CNG1–specific riboprobe for Northern blot (Figure 3B) and in situ hybridization (Figures 5 and 6) was derived. Bottom, intron-exon structure of CNGα1 channel gene. Black bars, coding regions; white bars, 5′ and 3′ untranslated regions; lines, introns. Anti-CNG1 is transcribed from the region of intron 9 and exon 10 of CNGα1 channel gene but in reverse orientation.
