In situ and in vitro analysis of α1D-adrenergic receptor C-terminal PDZ ligand:SCRIB truncation mutant interactions. (A–C). Biolayer interferometry (BLI) analyses of α1D-CT binding to SCRIB ΔPDZ4 (A), SCRIB ΔPDZ34 (B) and SCRIB PDZ34 (C). BLI data are presented as mean ± SEM, n = 3. (D) Co-immunoprecipitation of myc-α1D-AR with transfection vehicle (− vector), empty pGlue vector (+vector), TAP-SCRIB containing all 4 PDZ domains (WT), or sequentially truncated at the C-terminus (CT), PDZ domain 4 (ΔPDZ4), PDZ domain 3 (ΔPDZ34), PDZ domain 2 (PDZ1) or PDZ domain 1 (ΔPDZ) from HEK293 cell lysates. Shown are western blots of TAP-SCRIB constructs (top panel), myc-α1D-AR multimers (middle panel) and monomers (bottom panel). For full blots reference Supplemental Fig. 2.
