Figure 1From: The role of copeptin as a diagnostic and prognostic biomarker for risk stratification in the emergency department Cartoon of the 164-amino acid peptide precursor, preprovasopressin. Shows the signal sequence (white), AVP (dark green), neurophysin II (pale green) and copeptin (light green). Copeptin (CT-proAVP) is the C-terminal part of proAVP. Numbers indicate amino acids of the human protein. AVP: arginine vasopressin; CT-proAVP: C-terminal proAVP; signal: signal peptide.Back to article page
