Formatted abstract
Recycling of internalized receptors from endosomal compartments is essential for the receptors’ cell-surface homeostasis.
Sorting nexin 27 (SNX27) cooperates with the retromer complex in the recycling of proteins containing type I PSD95–Dlg–ZO1
(PDZ)-binding motifs. Here we define specific acidic amino acid sequences upstream of the PDZ-binding motif required for
high-affinity engagement of the human SNX27 PDZ domain. However, a subset of SNX27 ligands, such as the β2 adrenergic
receptor and N-methyl-d-aspartate (NMDA) receptor, lack these sequence determinants. Instead, we identified conserved
sites of phosphorylation that substitute for acidic residues and dramatically enhance SNX27 interactions. This newly identified
mechanism suggests a likely regulatory switch for PDZ interaction and protein transport by the SNX27–retromer complex.
Defining this SNX27 binding code allowed us to classify more than 400 potential SNX27 ligands with broad functional
implications in signal transduction, neuronal plasticity and metabolite transport.
