Type: Binary Subtype: Pre‑translational | |||||||
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
GRIK1_RAT | LIG_PDZ_Class_1 | 900 | 905 | Alternative splicing removes the PDZ-binding motif of Isoform Glur5-2 of Glutamate receptor ionotropic, kainate 1 (Grik1), abrogating binding to PRKCA-binding protein (Pick1). The ER-retention motif of Grik1 splice variants can be inhibited by PKC phosphorylation and association with a PDZ protein. It has also been shown that the PDZ domain-containing proteins Disks large homolog 4 (Dlg4) and Syntenin-1 (Sdcbp) are able to bind. | |||
GRIA2_RAT | LIG_PDZ_Class_2 | 878 | 883 | Alternative splicing removes the PDZ-binding motif of Glutamate receptor 2 (Gria2), abrogating binding to PRKCA-binding protein (Pick1). The presence of PDZ-binding motifs is also seen in the short isoforms of Gria3 (Isoform Flop of Glutamate receptor 3 (Gria3)) and Gria4 (Isoform 4C flop of Glutamate receptor 4 (Gria4)). PRKCA-binding protein (Pick1) recruits both Protein kinase C alpha type (Prkca) and Gria2 simultaneously, possibly allowing Pick1 to play a role in the selective targeting to and possible anchoring of GluRshort-containing AMPA receptors to intracellular membrane-associated Prkca. |
