N. Takamatsu et al., ACORN BARNACLE MEGABALANUS-ROSA LECTIN (BRA-3) - CDNA CLONING, GENE STRUCTURE AND SEASONAL-CHANGES OF MESSENGER-RNA AND PROTEIN-LEVELS, Gene, 128(2), 1993, pp. 251-255
We have isolated cDNA clones coding for a lectin (BRA-3) from the acor
n barnacle, Megabalanus rosa. Sequence comparison of the cDNA clones h
as revealed polymorphism in the BRA-3 mRNA, which results from single-
nucleotide (nt) differences at three positions. All three differences
are within the coding region and cause conservative amino acid (aa) ch
anges. The BRA-3 gene is composed of four exons, and the three single-
nt differences are located on different exons. In addition, the BRA-3
mRNA and BRA-3 protein levels increased during early summer in a simil
ar fashion, indicating that BRA-3 production is regulated mainly at th
e level of transcription.
