Comments Information

    • Introduction

    • Proadrenomedullin N-terminal 20 peptide (PAMP) is a biologically active molecule (20 amino acid residues) produced by post-translational enzymatic processing of the common precursor of adrenomedullin (AM), a 185-amino acid proadrenomedullin molecule. PMAP can bee found in various types. Function
