== Disease ==
[https://www.uniprot.org/uniprot/ADA10_HUMAN ADA10_HUMAN] Reticulate acropigmentation of Kitamura. The disease is caused by mutations affecting the gene represented in this entry.  Disease susceptibility is associated with variations affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/ADA10_HUMAN ADA10_HUMAN] Cleaves the membrane-bound precursor of TNF-alpha at '76-Ala-|-Val-77' to its mature soluble form. Responsible for the proteolytical release of soluble JAM3 from endothelial cells surface (PubMed:20592283). Responsible for the proteolytic release of several other cell-surface proteins, including heparin-binding epidermal growth-like factor, ephrin-A2, CD44, CDH2 and for constitutive and regulated alpha-secretase cleavage of amyloid precursor protein (APP) (PubMed:26686862, PubMed:11786905). Contributes to the normal cleavage of the cellular prion protein (PubMed:11477090). Involved in the cleavage of the adhesion molecule L1 at the cell surface and in released membrane vesicles, suggesting a vesicle-based protease activity (PubMed:12475894). Controls also the proteolytic processing of Notch and mediates lateral inhibition during neurogenesis (By similarity). Responsible for the FasL ectodomain shedding and for the generation of the remnant ADAM10-processed FasL (FasL APL) transmembrane form (PubMed:17557115). Also cleaves the ectodomain of the integral membrane proteins CORIN and ITM2B (PubMed:19114711, PubMed:21288900). May regulate the EFNA5-EPHA3 signaling (PubMed:16239146).[UniProtKB:O35598]<ref>PMID:11477090</ref> <ref>PMID:11786905</ref> <ref>PMID:12475894</ref> <ref>PMID:16239146</ref> <ref>PMID:17557115</ref> <ref>PMID:19114711</ref> <ref>PMID:20592283</ref> <ref>PMID:21288900</ref> <ref>PMID:26686862</ref>

== Publication Abstract from PubMed ==
Cleavage of membrane-anchored proteins by ADAM (a disintegrin and metalloproteinase) endopeptidases plays a key role in a wide variety of biological signal transduction and protein turnover processes. Among ADAM family members, ADAM10 stands out as particularly important because it is both responsible for regulated proteolysis of Notch receptors and catalyzes the non-amyloidogenic alpha-secretase cleavage of the Alzheimer's precursor protein (APP). We present here the X-ray crystal structure of the ADAM10 ectodomain, which, together with biochemical and cellular studies, reveals how access to the enzyme active site is regulated. The enzyme adopts an unanticipated architecture in which the C-terminal cysteine-rich domain partially occludes the enzyme active site, preventing unfettered substrate access. Binding of a modulatory antibody to the cysteine-rich domain liberates the catalytic domain from autoinhibition, enhancing enzymatic activity toward a peptide substrate. Together, these studies reveal a mechanism for regulation of ADAM activity and offer a roadmap for its modulation.
