Peripheral? Not Really! The Extracellular Arabinogalactan Proteins Function in Calcium Signaling
Arabinogalactan proteins (AGPs) are a family of extracellular proteoglycans that existed in land plants and algae (Johnson et al., 2017). AGPs are part of the hydroxyproline-rich glycoprotein (HRGP) superfamily that also includes extensins and proline-rich proteins. Based on the protein sequence, a glycosylphosphatidylinositol (GPI) anchor is predicted to be present at the C-terminus of many […]
