Genomic organization and chromosomal localization of mouse proteinase 3 (Myeloblastin)

Genomic organization and chromosomal localization of mouse proteinase 3 (Myeloblastin) Proteinase 3 (PR3), is a matrix-degrading serine proteinase expressed in different hematopoietic cell lineages. The PR3 protein appears to regulate the myeloid differentiation and was found to be the autoantigen associated with Wegener granulomatosis. We have isolated and characterized the gene for mouse PR3 (mPR3) and determined its chromosomal location. The gene has been localized to Chromosome (Chr) 10. Comparison of mouse PR3 genomic structure with that of its human counterpart indicates that: 1) the mPR3 gene spans 7 kb organized in 5 exons and 4 introns, 2) the codons of His-Asp-Ser of the catalytic site are conserved and spread out over different exons, similar to the human gene, and 3) the gene product encodes a pre-proform of the protein. Knowledge of the structure and chromosomal location of the mPR3 gene may help better the understanding of the temporal and cell-specific expression of mouse PR3. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Mammalian Genome Springer Journals

Abstract

Proteinase 3 (PR3), is a matrix-degrading serine proteinase expressed in different hematopoietic cell lineages. The PR3 protein appears to regulate the myeloid differentiation and was found to be the autoantigen associated with Wegener granulomatosis. We have isolated and characterized the gene for mouse PR3 (mPR3) and determined its chromosomal location. The gene has been localized to Chromosome (Chr) 10. Comparison of mouse PR3 genomic structure with that of its human counterpart indicates that: 1) the mPR3 gene spans 7 kb organized in 5 exons and 4 introns, 2) the codons of His-Asp-Ser of the catalytic site are conserved and spread out over different exons, similar to the human gene, and 3) the gene product encodes a pre-proform of the protein. Knowledge of the structure and chromosomal location of the mPR3 gene may help better the understanding of the temporal and cell-specific expression of mouse PR3.
