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 heterooligomers, 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 (aa) sequence, they differ significantly in their oligomeric structure, post-translational processing and subsequently cellular location, and substrate and peptide bond specificity (4). Human Meprin alpha subunit consists of a signal peptide (aa 1 to 21), a pro region (aa 22 to 65), and a mature chain (aa 66 to 746) containing the following domains: catalytic (aa 62 to 263), MAM (aa 264 to 433), MATH (aa 434 to 593), EGF-like (aa 670 to 710), transmembrane (aa 713 to 740), and cytoplasmic (aa 741 to 746).
