Drosophila Snx27 Interacts with the PDZ Binding Motifs Present in the C Termini of Fmi and Stbm
(A) Alignment of the C-terminal PDZ binding motifs of Drosophila Fmi and Stbm with the optimized sequence for PDZ binding motif recognition by the PDZ domain of SNX27.
(B–E) GFP-nanotrap immunoprecipitations of HEK293T cells transiently transfected with constructs encoding for GFP-tagged tail regions of Fmi and Stbm (GFP-Fmi wild-type [WT], B and D, and GFP-Stbm WT, C and E) or the corresponding constructs deleted for the last three amino acids of the PDZ binding motif (GFP-FmiΔPDZbm, B and D, and GFP-StbmΔPDZbm, C and E).
(B and C) Samples immunoblotted for the presence of endogenous human SNX27.
(D and E) Cells co-transfected with mCherry-tagged Drosophila Snx27 and samples immunoblotted with anti-mCherry. Data are representative of similar data derived from three independent biological replicates.
