In the acorn barnacle Megabalanus rosa, two types of galactose-binding
C-type lectins (BRA-2 and BRA-3) have been identified. Here, we repor
t the isolation and characterization of BRA-2 cDNA and genomic clones.
In contrast to the BRA-3 gene, which consists of four exons, BRA-2 is
encoded by a single exon, implying differences in the physiological r
oles of the two lectins.
