We have cloned and characterized the complete fibroin light chain gene from the silkworm Baekok-Jam, Bombyx mori, a recommended variety in Korea. It consists of seven exons and six introns. It consists of 14,663 nucleotides long with an open reading frame of 786 nucleotides that encodes a protein of 262 amino acid residues with a molecular mass of approximately 26,000 dalton. The amino acid alignment revealed that the Baekok-Jam fibroin light chain had 98.5 % protein sequence identity to J139 strain: differed at four amino acid positions (11, 46, 80 and 123). The Northern hybridization analysis showed that the Baekok-Jam fibroin light chain gene was specifically expressed in the posterior silk gland.
