P3NP

Meaning

Procollagen Type III N-terminal Peptide (P3NP) is a circulating biomarker that quantifies the synthesis of Type III collagen, a fundamental protein within the extracellular matrix of various tissues. This peptide represents the specific N-terminal propeptide fragment that is enzymatically cleaved and released into circulation during the post-translational processing of procollagen into mature collagen fibers.
