Neuronal migrations and axon fasciculation are disrupted in ina-1 integrin mutants.

Abstract excerpt

Integrins are heterodimeric cell surface receptors implicated in cell adhesion and signaling. Our analysis of C. elegans ina-1 alpha integrin mutants provides the first genetic evidence that migrating neurons require integrins. Mosaic analysis and expression studies show that ina-1 acts autonomously in cells to promote their migrations. Although axons generally extend to their normal targets in ina-1 mutants,...
