Complementary DNA clones for human glucocerebrosidase were isolated from a human hepatoma library in λgt11. The complete nucleotide sequence of the 1805-base pair cDNA insert has been determined. In addition to 5' and 3' untranslated regions (51 and 206 base pairs, respectively), the cDNA insert contains 1548 base pairs that completely encode human glucocerebrosidase. All possible N-linked glycosylation sites are identified. Examination of the 19 amino acids of the leader polypeptide beginning with the ATG at position 52 revealed a hydrophobic core and a carboxylterminal glycerine at the peptidase cleavage site, features consistent with the leader sequences described for other human translocated proteins. The M(r) of 57,000 calculated from the 516 amino acids deduced from cDNA sequence is in good agreement with that identified by immunoprecipitation following in vitro translation of human placental mRNA.
