Uptake of Alexa488 labeled transferrin normalized by the amount of surface transferrin receptor for each condition and against uptake for the wild-type cells in each experiment. Each value represents median fluorescence from at least 5000 cells (n = 12, mean ± SD). ∗∗∗ p > 0.001, ns = non-significant. One-way ANOVA with Tukey’s post hoc analysis. Bottom: Immunoblots showing PI3KC2α knockdown in wild-type and FCHSD2 KO cells. (B) Kymographs of HeLa FCHSD2-Venus stables silenced for PI3KC2α and control cells. Cells were transfected with mCherry-ClathrinLC 24 hs before imaging. Kymographs generated from 120 s movies at 1Hz. Note the elongated CCP lifetimes in PI3KC2α knockdown cells as described in Posor et al. (2013) . (C) Autoinhibition of FCHSD2. Representative images of a center slice from cells expressing different FCHSD2 truncation constructs and co-stained with phalloidin (Actin). The bar graph (upper right) shows the quantification of cellular protrusions/μm for each construct. The non-inhibited BAR domain produces many protrusions. Numbers inside bars represent number of cells measured. The line graph (bottom right) shows the fluorescence profile of sum intensity projections for cells expressing each construct. Due to the natural thinning of cells from their centers to the edge, a gradually decaying line indicates that the fluorescent protein is primarily cytosolic while a flat line with an abrupt fall on the cell edge indicates that the fluorescent protein is primarily bound to the membrane. While the presence of SH3-1 significantly reduces the generation of cellular protrusions generated by the FCHSD2 F-BAR, a significant fraction of the protein remains bound to the membrane (green line). Only the combined presence of SH3-1 and SH3-2 is capable to avoid promiscuous binding of the BAR domain to the membrane.

The amino acid sequence of DRI-Pep #20 comprises the nonnatural D-peptide RHQGK, the D-retroinverso (DRI)-isoform of the cell penetrating peptide Penetratin 1 (P1) and a glycine (G) linker. B , schematic representation of the fluorescence spectroscopy assays for the characterization of the interaction between DRI-Pep #20 (or PI3Kγ MP) and the recombinant fluorescein 5-maleimide–labeled PKA-RIIα (PKA-F5M). C , steady-state emission spectra of PKA-F5M in the presence of increasing concentrations of DRI-Pep #20 (0–20 μM). K D : dissociation constant. Inset, nonlinear fitting of the fluorescence intensity maxima obtained at various concentrations of DRI-Pep #20 for the monitoring of bio-labeled PKA. K A : association constant. D , for kinetic analysis, fluorescence spectra of PKA-F5M in the presence of increasing concentrations of DRI-Pep #20 or PI3Kγ MP (inset) were analyzed and fitted to a single exponential function to obtain the observed rate constant ( k obs ). The binding of DRI-Pep #20 or PI3Kγ MP to biolabeled PKA was investigated under pseudo -first-order conditions, and the kinetic constants, k on and k off , were determined.

G , cAMP concentrations in peritoneal macrophages from WT (in green ) and PI3Kγ −/− mice (in gray ) treated with DRI-Pep #20 (1–25 μM) for 30 min.

A, B. Low expression of PTEN and <t>PIK3C2A</t> were correlated with high risk, poor prognosis and shorter OS time. C, D. High expression of ITPA and BCL3 indicated high risk, poor prognosis and shorter OS time. Kaplan-Meier survival curves were also constructed to reveal the relationship between predicted risk of ccRCC patients and the OS time. The results showed that patients with high risk had a significantly shorter OS time than those with low risk (A-D). Green and red lines indicated low- and high-risk groups, respectively. P <0.05 was considered to be statistically significant. Cens: Censored; Event: Death; Prog. Idx.: Prognosis Index.

Cells were transfected with mCherry-ClathrinLC 24 hs before imaging. Kymographs generated from 120 s movies at 1Hz.

Representative images of a center slice from cells expressing different FCHSD2 truncation constructs and co-stained with phalloidin (Actin). The bar graph (upper right) shows the quantification of cellular protrusions/μm for each construct. The non-inhibited BAR domain produces many protrusions. Numbers inside bars represent number of cells measured. The line graph (bottom right) shows the fluorescence profile of sum intensity projections for cells expressing each construct. Due to the natural thinning of cells from their centers to the edge, a gradually decaying line indicates that the fluorescent protein is primarily cytosolic while a flat line with an abrupt fall on the cell edge indicates that the fluorescent protein is primarily bound to the membrane. While the presence of SH3-1 significantly reduces the generation of cellular protrusions generated by the FCHSD2 F-BAR, a significant fraction of the protein remains bound to the membrane (green line).

Figure Lengend Snippet: FCHSD2 Is Not Directly Recruited to CCPs by PI3KC2α or Its Kinase Activity, Related to Figure 2 (A) Top: Transferrin uptake assay by flow cytometry comparing wild-type and FCHSD2 KO cells silenced for PI3KC2α. Uptake of Alexa488 labeled transferrin normalized by the amount of surface transferrin receptor for each condition and against uptake for the wild-type cells in each experiment. Each value represents median fluorescence from at least 5000 cells (n = 12, mean ± SD). ∗∗∗ p > 0.001, ns = non-significant. One-way ANOVA with Tukey’s post hoc analysis. Bottom: Immunoblots showing PI3KC2α knockdown in wild-type and FCHSD2 KO cells. (B) Kymographs of HeLa FCHSD2-Venus stables silenced for PI3KC2α and control cells. Cells were transfected with mCherry-ClathrinLC 24 hs before imaging. Kymographs generated from 120 s movies at 1Hz. Note the elongated CCP lifetimes in PI3KC2α knockdown cells as described in Posor et al. (2013) . (C) Autoinhibition of FCHSD2. Representative images of a center slice from cells expressing different FCHSD2 truncation constructs and co-stained with phalloidin (Actin). The bar graph (upper right) shows the quantification of cellular protrusions/μm for each construct. The non-inhibited BAR domain produces many protrusions. Numbers inside bars represent number of cells measured. The line graph (bottom right) shows the fluorescence profile of sum intensity projections for cells expressing each construct. Due to the natural thinning of cells from their centers to the edge, a gradually decaying line indicates that the fluorescent protein is primarily cytosolic while a flat line with an abrupt fall on the cell edge indicates that the fluorescent protein is primarily bound to the membrane. While the presence of SH3-1 significantly reduces the generation of cellular protrusions generated by the FCHSD2 F-BAR, a significant fraction of the protein remains bound to the membrane (green line). Only the combined presence of SH3-1 and SH3-2 is capable to avoid promiscuous binding of the BAR domain to the membrane. Data is shown as mean ± SD in bar graph and as ± SEM in fluorescence profiles. ∗∗∗ p > 0.001, ns = non-significant. One-way ANOVA with Tukey’s post hoc analysis.

Figure 6. Experimental workflow. IP3K2 expression was reduced in flies overexpressing human α-synuclein. Geotaxis and lifespan PD-related phenotypes were measured (A). ITPKB was quantified in SK-N-SH cells overexpressing wild-type or mutated A53T or A30P α-synuclein by western blot (B, top). ITPKB protein level was measured also in the cytoplasm and in the nucleus of cells, separately (B, bottom). ITPKB and SNCA mRNA levels were quantified in cortex from PD patients and controls (C).

A, B. Low expression of PTEN and PIK3C2A were correlated with high risk, poor prognosis and shorter OS time. C, D. High expression of ITPA and BCL3 indicated high risk, poor prognosis and shorter OS time. Kaplan-Meier survival curves were also constructed to reveal the relationship between predicted risk of ccRCC patients and the OS time. The results showed that patients with high risk had a significantly shorter OS time than those with low risk (A-D). Green and red lines indicated low- and high-risk groups, respectively. P <0.05 was considered to be statistically significant. Cens: Censored; Event: Death; Prog. Idx.: Prognosis Index.
