21646356 Processing of APP by meprin beta was subsequently validated using in vitro and in vivo approaches. N-terminal APP fragments of about 11 and 20 kDa were found in human and mouse brain lysates but not in meprin beta(-/-) mouse brain lysates
20953144 Demonstrate that the metalloprotease meprin beta and gamma-ENaC associate directly through cytoplasmic domains.
20806899 Cystatin C was an inhibitor for human meprin alpha(K(i) = 8.5 x 10(-6) M) but, interestingly, not for meprin beta.

19748582 data indicate that, at least under pathological conditions, meprinbeta might attack specific functional sites in tenascin-C that are important for its oligomerization and anti-adhesive activity
17195012 Mephrin beta induced a dramatic change in cell morphology and reduced the cell number, indicating a function in terminal differentiation, whereas meprin alpha did not affect cell viability, and may play a role in basal keratinocyte proliferation.
12941954 two different metalloprotease activities are responsible for the constitutive and the PMA-stimulated hmeprinbeta shedding
12387727 results show that the O-linked carbohydrate side chains in hmeprinbeta are clustered around a 13 amino acid sequence that contains the main cleavage site for proteolytic processing of the subunit
