  • 功能：
    Digestive protease that cleaves proteins preferentially after an Arg residue and has proteolytic activity toward Kunitz-type trypsin inhibitors.

    3. Study developed a new high resolution crystal structure of mesotrypsin complexed with diminazene through a structure-based molecular docking screen that could help facilitate derivatization efforts, addressing current pan-inhibition of human trypsins through rigidification of diminazene to select for a conformation that maximizes interactions with the non-conserved Arg-193 residue.

    4. Data show that silencing tumor-endothelial cells (EC) for trypsinogen 4 accumulated tissue factor pathway inhibitor-2 (TFPI-2) in the matrix. PMID: 26318044
    5. These findings suggest that inhibitor cleavage represents a functional adaptation of mesotrypsin that may have evolved in response to positive selection pressure. PMID: 26175157

    8. Mesotrypsin generated saposins A-D from prosaposin, and mature caspase-14 contributed to this process by activating mesotrypsinogen to mesotrypsin. Knockdown of these proteases markedly down-regulated saposin A synthesis in skin equivalent models. PMID: 24872419

    28. Here, we report that nexin-1 inhibits trypsin-4, and forms stable complexes only with this trypsin-isoenzyme. This result suggests that nexin-1 could modulate trypsin activity in brain where both nexin-1 and trypsin-4 are expressed. PMID: 19249338
