Predicted non-coding RNAs (ncRNA) derived from the Little Skate Hoxa cluster. Non-coding RNA1 (A) is found only in Leucoraja erinacea. Non-coding RNA2 (B) is located in the intron of the Hoxa10 gene and is found only in Little Skate, Horn Shark, Elephant Shark and Indonesian coelacanth. Non-coding RNA3 (C) is mir196b and is found in all vertebrates examined to date. Ler -- Little Skate, Hfr -- Horn Shark, Cmi - Elephant shark, Hsa -- human, Lme -- Indonesian coelacanth.
