<p>A new form of human glandular kallikrein-1 (hK2) has been found by cloning a prepro-hK2 cDNA from a human prostate cancer tissue cDNA library. This form of hK2 differs in sequence from the previously deduced sequence for hK2 in that Arg226 is substituted by Trp. Use of a baculovirus expression vector is described for obtaining hK2 proteins, including Arg226-hK2 as an active mature protein directly from a culture medium.</p> |
