The Type I Collagen Fragments ICTP and CTX Reveal Distinct Enzymatic Pathways of Bone Collagen Degra
Figure FIG. 1. Schematic representation of the CTX and ICTP epitopes used as markers of bone resorption on type I collagen and cathepsin K (Cat K) cleavage sites. CTX epitope is constituted by an eight amino acid sequence on the C-telopeptide of α1. The I...
