Background: PCPE-1

Procollagen C‑endopeptidase enhancers, known as PCPEs or PCOLCEs, are secreted extracellular matrix glycoproteins that consist of two CUB domains and one NTR domain. They are known to stimulate enzymatic cleavage of procollagens I‑III by the BMP‑1/tolloid family of metalloproteases, also known as procollagen C‑proteinases (1). PCPE‑1 is expressed primarily by interstitial connective tissues such as tendons, calvaria, and skin (2). Although BMP‑1/tolloid proteinases are involved in processing of multiple extracellular proteins, the enhancer activity of PCPE‑1 is specific to procollagens since it has no effect on BMP‑1/tolloid cleavage of other substrates (3). It is thought that PCPE‑1 enhances cleavage of procollagens by binding to the substrate and inducing a conformation change in the substrate (3), although interaction between PCPE‑1 and full‑length BMP‑1/tolloid proteinases has also been reported (4).
