Overlapping cDNA clones, totaling 3.3 kilobases (kb) in length, which
encode over 50% of the human erythrocyte beta-spectrin subunit, were
isolated by antibody screening of a lambda gt11 expression library
constructed from human fetal liver mRNA. The amino acid sequence of the
C-terminus of beta-spectrin was derived. The size of beta-spectrin mRNA in
human erythroleukemia cells was found to be 7.5 kb. Erythrocyte beta-
spectrin is encoded by a gene located on human chromosome 14, as determined
by cDNA hybridization to human X mouse somatic cell hybrids.
