title: Localization of the gene for the erythroid anion exchange protein, band 3 (EMPB3), to human chromosome 17.
abstract: We have isolated genomic DNA clones which code for the human erythroid membrane protein band 3 (EMPB3). The identification of the gene has been confirmed by comparison of the amino acid sequence derived from the nucleotide sequence for two restriction fragments from the 5' end of the gene. Two exons have been identified. One exon encodes 20 amino acids which are identical to residues 36 to 56 of the band 3 protein, and the other encodes 44 amino acids homologous to residues 118 to 162. Southern analysis of genomic DNA derived from a panel of rodent-human somatic cell hybrids, which retain different complements of human chromosomes, with band 3 probes has allowed us to localize EMPB3 to human chromosome 17. The gene has been further localized between 17q21 and qter by analysis of DNA from somatic cell hybrids which carry derivative chromosomes from translocations involving chromosome 17 and either chromosome 15 or 21.
