| abstractText | Serine proteases are important granule constituents in several of the major hematopoietic cell lineages. We present here the nucleotide sequence of the gene encoding mouse mast cell protease 8 (mMCP-8). mMCP-8 was initially isolated as a cDNA from a mouse mast cell line, but has recently been found to be expressed primarily by mouse basophils. mMCP-8 and its rat homologues, rMCP-8, -9, and -10, form a new group of mast cell/basophil proteases, which are more closely related to the T-cell granzymes and neutrophil cathepsin G than to the mast cell tryptases and chymases. A dot matrix comparison of the mMCP-8 gene with other closely related hematopoietic serine protease genes shows detectable homology only in the exonic regions of the genes. No indication for conservation in the promoter region or introns was observed. This latter finding indicates that the upstream regulatory region has evolved at a relatively high rate. However, despite the low degree of direct sequence conservation, no major differences in the sizes of introns or exons were observed between mMCP-8 and genes for the closest related hematopoietic serine proteases, the mouse T-cell granzymes and cathepsin G, indicating that after evolutionary separation from the T-cell granzymes and cathepsin G, the majority of mutations primarily involved single base pair substitutions or short insertions or deletions. |
