Identification of SPPL2c substrates in HEK293 cells.Figure 1A) Volcano plot of proteome analysis. Plotted is the negative log10 of the p-value (y-axis) versus the log2 LFQ ratio of SPPL2c overexpressing and control cells (x-axis) of a given identified protein. A permutation based FDR correction for multiple hypotheses was applied (p = 0.05; s0 = 0.1; dashed line). Open grey circles indicate proteins not-significantly altered in SPPL2c expressing cells, red circles significantly altered proteins after FDR correction. Filled red circles indicate type IV membrane proteins and filled blue circles with red line and blue names type II proteins altered in SPPL2c expressing cells, n=6 biological repl. per cell line. B) Pathway analysis of SPPL2c candidate substrates. All type II and type IV membrane proteins significantly decreased in the proteomic analysis following overexpression of SPPL2c (see Table 1) were uploaded on the online STRING 10.5 software (https://string-db.org/). Interaction networks of the candidate substrates are depicted and the thickness of the lines indicates the degree of confidence in the prediction of the interaction. C) Western Blot of selected type IV SPPL2c candidate substrates. Endogenous protein levels of VAPA, VAPB, VAMP8, Syntaxin 8, 18 (Stx8 & Stx18) and Membrin (encoded by the gene Golgi SNAP Receptor Complex Member 2, GOSR2) were analyzed in HEK293 cells ectopically expressing wild type SPPL2c (SPPL2c WT) or a catalytically inactive SPPL2c (SPPL2c D/A). Non-transfected cells (-) or stably transfected but non-induced SPPL2c wt cells (n/i) served as controls. VAPA, VAPB, VAMP8, Stx8 and Membrin protein levels were decreased in SPPL2c expressing cells but not in control or SPPL2c D/A expressing cells. For Stx18 a cleavage product was detected in SPPL2c WT expressing cells. Expression levels of SPPL2c are depicted and Calnexin serves as loading control.
