- Abstract
Myeloblastin is a serine protease that has been identified in the human leukemia cell line HL-60. Down-regulation of this protease can inhibit proliferation and induce differentiation of promyelocyte-like human leukemic cells. Proteinase 3, a serine protease of human neutrophils, has been identified as the Wegener autoantigen. A high level of homology between myeloblastin and proteinase 3 has suggested that they may be a single serine protease. We have recently completed the 5'-terminal nucleotide sequence of proteinase 3 and shown that its mRNA was also expressed in HL-60 cells and in cells from patients with acute myeloid leukemia. Here we demonstrate that myeloblastin and proteinase 3 are encoded by a single mRNA.
