A complete full-length non-LTR retrotransposon, BMC1, on the W chromosome of the silkworm, Bombyx mori

In the silkworm, Bombyx mori, a non-long terminal repeat (non-LTR) retrotransposon, BMC1, is considered to be a LINE (long interspersed nuclear element)-like element. So far, a BMC1 containing two intact open reading frames (ORFs) has not been found. However, we discovered a complete full-length BMC...

Zusammenfassung:In the silkworm, Bombyx mori, a non-long terminal repeat (non-LTR) retrotransposon, BMC1, is considered to be a LINE (long interspersed nuclear element)-like element. So far, a BMC1 containing two intact open reading frames (ORFs) has not been found. However, we discovered a complete full-length BMC1 on the W chromosome. This BMC1 is 5091 bp and contains a 5' untranslated region (5'-UTR), two intact ORFs, and 3'-UTR which terminates in a poly(A) tail. ORF1 encodes a putative nucleic acid-binding protein, while ORF2 encodes a protein containing an endonuclease domain and a reverse transcriptase domain.
