Using a PCR-based strategy, we have determined the complete cDNA sequence encoding hedgehog plasminogen (Plg). The 2700-nucleotide cDNA (corresponding to a 2.9-kb liver-derived transcript) encodes an open reading frame of 811 amino acids which shares 74-76% identity with Plg characterized from mouse, human and rhesus monkey. Residues corresponding to the catalytic triad, tPA-cleavage site, as well as seven of the eight lysine-binding residues in kringle IV are conserved in the hedgehog. However, potential N-linked glycosylation sites which have been reported in human and rhesus Plg are not present in analogous positions in the hedgehog Plg sequence.
