Fig. 1. The structure of the plx-1 gene and its product. (A) The primary structure of PLX-1 aligned with the Drosophila PlexA and the mouse plexin-A2 sequences. (B) The similarity (%) between each region of PLX-1 and that of Drosophila PlexA and mouse plexin-A2. (C) A scheme showing the structure of the plx-1 gene, deletions, the construct plx-1::egfp used in the expression analysis and the PCR products used for rescue experiments. DDBJ Accession Number for the plx-1 cDNA is AB080022.
