Chaperone for wingless signalling and trafficking of LDL receptor Mesd is a family of highly conserved proteins found from nematodes to humans. The final C-terminal residues, KEDL, are the endoplasmic reticulum retention sequence as it is an ER protein specifically required for the intracellular trafficking of members of the low-density lipoprotein family of receptors (LDLRs). The N- and C-terminal sequences are predicted to adopt a random coil conformation, with the exception of an isolated predicted helix within the N-terminal region, The central folded domain flanked by natively unstructured regions is the necessary structure for facilitating maturation of LRP6 (Low-Density Lipoprotein Receptor-Related Protein 6 Maturation). |
