Background: Meprin alpha Subunit/MEP1A

Meprins are multimeric proteases composed of alpha and beta subunits, which are members of the astacin family of zinc endopeptidases (1, 2). Both subunits form disulfide‑linked homo- or hetero-oligomers, which are also referred to as Meprin A (composed of alpha subunits with or without beta subunits) and Meprin B (composed of beta subunits only) (3). Although the two subunits share 42% identity in their amino acid sequence, they differ significantly in their oligomeric structure, post-translational processing and subsequently cellular location, and substrate and peptide bond specificity (4). The 760 amino acid sequence of mouse meprin alpha subunit precursor consists of a signal peptide (residues 1‑33), a pro region (residues 34‑77), and a mature chain (residues 78‑760) containing the following domains, catalytic (residues 78‑275), MAM (residues 276‑445), MATH (residues 447‑607), EGF-like (residues 684‑724), transmembrane (residues 727‑754), and cytoplasmic (residues 755‑760) (5). The pro enzyme terminating at residue 615 was expressed and the secreted protein purified from conditioned medium. The molecular masses of recombinant mouse MEP1A are similar to those observed for the alpha subunit of rat Meprin A (6).
