The nucleotide sequence and in situ localization of a gene for a dimeric haemoglobin from the midge Chironomus thummi piger.
A cluster containing at least four globin genes was isolated by screening an lambda EMBL3 genomic DNA library of the midge Chironomus thummi piger (Ctp) with a heterologous haemoglobin (Hb) gene IV (HbIV) probe from Chironomus thummi thummi (Ctt). This globin gene cluster was localized by in situ hybridization to chromosome II. One globin gene together with its 5'- and 3'-flanking regions has been sequenced. It can be deduced from the sequence that it is a new member of the dimeric HbVIIB family. The Ctp HbVIIB-5 gene displays 91.8% nucleotide sequence homology to a HbVIIB cDNA sequence, reported previously. There is no evidence for intron/exon structure in the Ctp HbVIIB-5 gene.
