A Disintegrin And Metalloprotease 10 is a ADAM family member that cleaves many proteins including TNF-alpha and E-cadherin. Members of the ADAM family are cell surface proteins with a unique structure possessing both potential adhesion and protease domains. ADAM10 is a sheddase, and has a broad specificity for peptide hydrolysis reactions. New data on the ADAM10 shedding of ephrin/eph complex associated with Eph on one cell surface has determined that ADAM10 cleaves ephrin, within the ephrin/eph complex, formed between two cell surfaces. When ephrin is freed from the opposing cell, the entire ephrin/eph complex is endocytosed. This shedding in trans had not been previously shown, but may well be involved in other shedding events.
