Alpha spectrin is essential for morphogenesis and body wall muscle formation in Caenorhabditis elegans.

Abstract excerpt

A common feature of multicellular animals is the ubiquitous presence of the spectrin cytoskeleton. Although discovered over 30 yr ago, the function of spectrin in non-erythrocytes has remained elusive. We have found that the spc-1 gene encodes the only alpha spectrin gene in the Caenorhabditis elegans genome. During embryogenesis, alpha spectrin localizes to the cell membrane in most if not all cells, starting at...
