Recombinant Human Meprin alpha Subunit/MEP1A Protein

Cat. No.: rp148696
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. His Tag ? His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. ≥95%(SDS-PAGE)

Overview

Meprins are multimeric proteases composed of alpha and beta subunits, which are members of the astacin family of zinc endopeptidases. 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). 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. The 746 amino acid sequence of human meprin alpha subunit precursor consists of a signal peptide (residues 1 to 21), a pro region (residues 22 to 65), and a mature chain (residues 66 to 746) containing following domains, catalytic (residues 62 to 263), MAM (residues 264 to 433), MATH (residues 434 to 593), EGF-like (residues 670 to 710), transmembrane (residues 713 to 740), and cytoplasmic (residues 741 to 746). The pro enzyme terminating at residue 601 was expressed and the secreted protein purified from conditioned medium. The molecular masses of recombinant human MEP1A are similar to those observed for the alpha subunit of rat Meprin A.
