A Valuable Target for Therapy: The Metalloproteinase ADAM10.

A special kind of posttranslational process known as proteolytic cleavage controls the half-lives and functions of several extracellular and intracellular proteins. The metalloproteinase ADAM10 has attracted attention because it cleaves a growing amount of protein substrates close to the extracellular membrane leaflet. The process known as "ectodomain shedding" controls the turnover of certain transmembrane proteins that are essential for receptor signaling and cell adhesion. It may trigger nuclear transport, intramembrane proteolysis, and cytoplasmic domain signaling. Additional human illnesses linked to ADAM10 include cancer, immune system malfunction, and neurodegeneration. The difficulty in targeting proteases for medicinal reasons stems from the many substrates that these enzymes, particularly ADAM10, have. It is usually necessary to precisely identify the therapeutic beneficial window of use since blocking or accelerating a particular protease activity is linked with undesirable side effects. More knowledge of the regulatory pathways governing ADAM10 expression, subcellular localization, and activity will probably lead to the identification of viable therapeutic targets, enabling more targeted and precise manipulation of the enzyme's proteolytic activity.
