The results of hybridization analyses using cDNA probes for mouse and human alpha-spectrin mRNA indicate that a single gene encodes the alpha-subunit of erythrocyte spectrin. Sequencing of the cDNA clones showed that they code for 370 amino acids (aa) covering three repeat domains close to the C terminus of alpha-spectrin. The cloned cDNAs will now permit the isolation of the alpha-spectrin gene and should lead to the characterization of the genetic aspects in human hereditary anemias in which alpha-spectrin has been characterized as the site of the molecular defect.

Abstract
The results of hybridization analyses using cDNA probes for mouse and human alpha-spectrin mRNA indicate that a single gene encodes the alpha-subunit of erythrocyte spectrin. Sequencing of the cDNA clones showed that they code for 370 amino acids (aa) covering three repeat domains close to the C terminus of alpha-spectrin. The cloned cDNAs will now permit the isolation of the alpha-spectrin gene and should lead to the characterization of the genetic aspects in human hereditary anemias in which alpha-spectrin has been characterized as the site of the molecular defect.
