The gene structure of tetranectin, a plasminogen binding protein

Abstract

The gene for human tetranectin was isolated from a genomic library with a mixture of degenerate oligonucleotide probes. The gene is about 12 kbp and contains two intervening sequences. The gene encodes a protein of 202 amino acid residues, with a signal peptide of 21 amino acid residues, followed by the tetranectin sequence of 181 amino acid residues. Northern blot analysis revealed that tetranectin mRNA was present in all eight tissues tested with the highest concentration in lung. Southern blot analysis showed hybridization to two genes. Further investigations are needed to determine whether the genes are allelic or non-allelic.
