產品介紹 :   Meprins are multidomain zinc metalloproteases that are highly expressed in mammalian kidney and intestinal brush border membranes, and in leukocytes and certain cancer cells. They are involved in the hydrolysis of a variety of peptide and protein substrates, and have been implicated in cancer and intestinal inflammation. Mature meprins are oligomers of evolutionarily related, but separately encoded alpha and/or beta subunits. Homooligomers of alpha subunit are secreted, whereas, oligomers containing the beta subunit are plasma membrane-bound. This gene encodes the beta subunit. Targeted disruption of this gene in mice affects embryonic viability, renal gene expression profiles, and distribution of the membrane-associated alpha subunit in kidney and intestine.

Function:

Membrane metallopeptidase that sheds many membrane-bound proteins. Known substrates include: FGF19, VGFA, IL1B, IL18, procollagen I and III, E-cadherin, KLK7, gastrin, ADAM10, tenascin-C. The presence of several pro-inflammatory cytokine among substrates implicate MEP1B in inflammation. It is also involved in tissue remodeling due to its capability to degrade extracellular matrix components.

Subunit:

Homotetramer consisting of disulfide-linked beta subunits, or heterotetramer of two alpha and two beta subunits formed by non-covalent association of two disulfide-linked heterodimers By similarity. Interacts with MBL2 through its carbohydrate moiety. This interaction may inhibit its catalytic activity.

Subcellular Location:

Cell Membrane; single-pass type I membrane protein.

Tissue Specificity:

The major site of expression is the brush border membrane of small intestinal and kidney epithelial cells.

Post-translational modifications:

N-glycosylated; contains high mannose and/or complex biantennary structures. Ref.6 Ref.14

O-glycosylation protect the C-terminal region from proteolytic cleavage and diminish secretion, this seems to be specific to human.

Proteolytically activated by trypsin in the intestinal lumen and kallikrein-related peptidases in other tissues.

Similarity:

Belongs to the peptidase M12A family.

Contains 1 EGF-like domain.

Contains 1 MAM domain.

Contains 1 MATH domain.
