Drosophila laminin: Sequence of B2 subunit and expression of all three subunits during embryogenesis

Research output: Contribution to journalArticle


In a previous study, we described the cloning of the genes encoding the three subunits of Drosophila laminin, a substrate adhesion molecule, and the cDNA sequence of the B1 subunit (Montell and Goodman, 1988). This analysis revealed the similarity of Drosophila laminin with the mouse and human complexes in subunit composition, domain structure, and amino acid sequence. In this paper, we report the deduced amino acid sequence of the B2 subunit. We then describe the expression and tissue distribution of the three subunits of laminin during Drosophila embryogenesis using both in situ hybridization and immunolocalization techniques, with particular emphasis on its expression in and around the developing nervous system.
