Procollagen Type I C-Terminal Peptide

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** This polypeptide is comprised of the carboxy-terminal portions of procollagen, which are proteolytically removed by bone morphogenetic protein 1 during the intracellular formation of type I collagen fibrils. Increased plasma or serum concentrations of these peptides are associated with both fibrillogenesis of type I collagen and bone formation.

**Synonyms:** - Collagen Type 1 C-Terminal Propeptide - Collagen Type I C-Terminal Propeptide - P1CP - PICP - Procollagen Type 1 C-Terminal Peptide
