Mast Cell Protease-11 (MCP-11) is encoded by Prss34, one of 13 genes on mouse chromosome 17A3.3 that correspond to functional trypsin-like serine proteases (1). The deduced amino acid sequence of mouse MCP-11 consists of 318 residues with a signal peptide (residues 1 to 19), a pro region (residue 20 to 34), and a catalytic domain (35 to 318). The mRNA is preferentially expressed in spleen and bone marrow. The mouse MCP-11 (residues 20 to 318) was expressed in the NS0 cells with a foreign signal peptide. After being treated with thermolysin, the purified enzyme is active against a peptide substrate described in the Activity Assay Protocol. Apparently, the human gene corresponding to Prss34 encodes a protein that is not enzymatically active due to a mutation that leads to a premature translation termination codon.
