abstract = "A disintegrin and metalloproteinase (ADAM) 10 is a type I transmembrane glycoprotein responsible for the ectodomain shedding of a range of proteins including the amyloid precursor protein implicated in Alzheimer's disease. In this study we demonstrate that ADAM10 itself is subject to shedding by one or more ADAMs. Expression of epitope-tagged wild-type ADAM10 in SH-SY5Y cells enabled the detection of a soluble ectodomain in conditioned medium. Shedding of the ADAM10 ectodomain was inhibited by a known ADAM inhibitor with a reciprocal accumulation of the full-length mature protein in both cell lysates and extracellular membrane vesicles. Shedding was also stimulated by phorbol ester treatment of cells. A glycosylphosphatidylinositol-anchored form of ADAM10 lacking the cytosolic, transmembrane and alpha-helical juxtamembrane regions of the wild-type protein was shed in a similar manner. Furthermore, a truncated soluble ADAM10 construct, although correctly post-translationally processed and catalytically active against a synthetic peptide substrate, was incapable of shedding cell-associated amyloid precursor protein. Finally, we show that ADAM9 is, at least in part, responsible for the ectodomain shedding of ADAM10. In conclusion, this is a new mechanism by which levels of ADAM10 are regulated and may have implications in a range of human diseases including Alzheimer's disease.",
