Websites within a neural circuit. PTLs of the MAG (Maleimide-Azobenzene-Glutamate) family have been successfully used to engineer light-gated iGluRs, termed LiGluRs (Volgraf et al., 2006; Gorostiza et al., 2007) and mGluRs, termed LimGluRs (Levitz et al., 2013). LiGluR is based on the kainate receptor WebLeft: Chemical structures of the PTL maleimide azobenzene glutamate (MAG) in the trans and cis configurations. The azobenzene moiety is highlighted in shaded grey. Right, upper part: Schematic representation of heteromeric GluK2/K5 kainate receptors. MAG is covalently attached to an engineered cysteine residue on the GluK2 subunit (light grey).
