- Western blot analysis of Arf6 was performed by loading 50 µg of various whole cell lysate onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with 5% Milk/TBST for at least 1 hour. Membranes were then probed with a rabbit polyclonal antibody recognizing Arf6 (Product # PA1-093) at a dilution of 1:1000 overnight at 4°C on a rocking platform. Membranes were then washed in TBS-0.1%Tween 20 and probed with a goat anti-rabbit-HRP secondary antibody (Product # 31460) at a dilution of 1:10000 for at least one hour. Membranes were washed and chemiluminescent detection was performed using Super Signal West Pico (Product # 34080).

- Knockdown of ARF6 was achieved by transfecting MDA-MB-231 with ARF6 specific siRNAs (Silencer® select Product # S1565, S1566). Western Blot analysis (Fig. a) was performed using Whole cell extracts from the ARF6 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The Blot was probed with ARF6 Polyclonal Antibody (Product # PA1-093, 1:1000 ) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000). Densitometric analysis of this western Blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to ARF6.

- Immunohistochemistry was performed on normal biopsies of deparaffinized human heart tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:20 with a Rabbit Polyclonal Antibody recognizing Arf6 (Product # PA1-093) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

- Fig 6 Arf6 is recruited by R . typhi RalF and is required for infection. (A) Ectopically expressed RalF RtFL co-localizes with Arf6 but not Arf5. HeLa cells co-expressing EYFP, EYFP-RalF RtFL or EYFP-RalF RbFL and mRFP-Arf6 (left) or -Arf5 (right) were fixed with 4% para-formaldehyde. Nuclei were stained with DAPI (blue). (Scale bar: 10 mum). (B) RalF RtFL pull-down of Arf6. Lysates from HEK293T cells expressing mRFP-Arf5 or -Arf6 were incubated with HisPur Cobalt resin bound with rHis-RalF RtFL or resin alone. Bound proteins were eluted with imidazole and analyzed by protein immunoblot using antibodies as indicated. (C) Arf6 is recruited during R . typhi entry. HeLa cells expressing mRFP-Arf5 or -Arf6 (red) were infected with partially purified R . typhi (MOI ~100). Ten minutes post infection, cells were fixed and R . typhi detected with anti- R . typhi serum (green). DAPI (blue) is shown in the merged image. Boxed regions are enlarged to show detail. White arrowheads indicate R . typhi . (Scale bar: 5 mum). (D) Arf6 knockdown inhibits R . typhi infection. HeLa cells transfected with negative, Arf6, or Arf5 siRNA were infected with partially purified R . typhi (MOI ~100). At 2 hrs post infection, cells were fixed, plasma membrane stained with Alexa Fluor 594 wheat germ agglutinin, and R . typhi detected with rat anti- R . typhi serum and Alexa Fluor 488 anti-rat antibody. The number of R . typhi per host cell was counted for 100 host cells for three independent experiments.

- Figure 3 Secretion of sFlt1 from endothelial cells requires functional Arf6, Arf1, and Rab11 GTPases. A-F : EC-sFlt1 cells were nucleofected with plasmid constructs expressing dominant-negative forms of Arf1, Arf6, Rab5, Rab6, Rab 8, syntaxin 4, syntaxin 6, and syntaxin 16. Similarly, in a separate study EC-sFlt1 cells were nucleofected with scramble oligonucleotide or siRNAs against Arf1 , Arf6 , and Rab11a . Media containing nucleofection complexes were replaced with fresh media 8 hrs post-nucleofection. At 36 hrs post-nucleofection, secreted and intracellular sFlt1 were immunoprecipitated from spent culture media and cell lysates using the anti-v5 Ab. ( A , C ) Representative blot shows relative expression of sFlt1-v5 in cell lysates and secreted in culture media. B , D : Band densities from experiments as in A, C were quantified by densitometric analysis. Secretion of sFlt1-v5 was calculated as the ratio of desitometric band intensity values of secreted to intracellular Flt1; this ratio was set at 1 for mock-transfected control EC-sFlt1 cells. The data are the means +- SEM from three independent experiments. E : EC-sFlt1 cells were transiently transfected with indicated dominant-negative plasmid constructs. After 24 hrs cells were fixed, permeabilized, and labeled with anti-v5 Ab to detect cell-associated sFlt1-v5. Representative images obtained by epifluorescence microscopy show localization of sFlt1-v5. F : Quantification of intracellular retention of sFlt1-v5 upon inhi

- Figure 6. The levels of activated Arf6 in cortical tissue are elevated because of Iqsec2 KO. (A) Biochemical assays to measure the levels of activated Arf6 (G-LISA) undertaken in cortical tissues of animals across postnatal development between 2 and 9 mo of age show that (A) the levels of activated Arf6 in wild-type male mice (WT/black) (n = 4) are elevated in age-matched wild-type female mice (WT/grey) (n = 5). (B) Iqsec2 KO hemizygous males (KO/blue, n = 6) and heterozygous KO females (Het/pink; n = 9) both display increased levels of activated Arf6 compared with the sex-matched wild-type controls listed above. (C) The abundance of Arf6 protein measured by immunoblot was not significantly different between any genotype groups. The Iqsec2 KO animals with observed seizures are denoted by stars. Mean (+-SEM) data presented, where * indicates significance between WT female control and HET/KO, P < 0.05, 2-tailed, unpaired t test.
