The structures shown represent best estimates of the gene structures for four key ECM proteins involved in axonal guidance (netrin, slit), synapse formation (agrin) and neuroblast positioning (reelin). These predictions are based on the gene predictions listed, linkage in the current interim assembly and additional Genewise predictions on the scaffolds containing these predictions. Given the current state of the genome assembly and the presence of haplotype pairs, these predictions must be viewed as provisional and need confirmation by cDNA analyses. Nonetheless, it seems clear that good orthologs of each of these genes exist in the sea urchin genome. Also listed are the potential cellular receptors for each of these proteins. For information about the SMART domains presented in this figure, see Suppl. Figure 16.
