Article Title: Two Heterozygous Mutations in NFATC1 in a Patient with Tricuspid Atresia
Journal: PLoS ONE

Figure Legend Snippet: A- The missense SNPs lead to a P66L substitution at the N-terminal region of the protein near the calcineurin-docking site (Cln binding), and to a I701L substitution at the C-terminal region downstream of the Rel Homolgy Domain (RHD). The schematic represents isoform A, the most abundant NFATC1 protein with 717 amino acids, a transactivation domain (TAD) at the N-terminus, and a DNA binding domain at the C-terminus. (NLS = nuclear localization signal, NES = nuclear export signal, and SP = Serine-Proline). B- The NFATC1 secondary structures were predicted and visualized by the Discovery Studio program (Acclerys Inc.). The results demonstrate the formation of a new beta-sheet in the P66L mutant and a deletion of a beta-sheet in the I701L mutant as compared to the wild type protein.

Figure Legend Snippet: A- Immunofluorescence of HeLa cells transfected with plasmids encoding for the Wt NFATC1 and NFATC1 Mutants (P66L, I701L, P66L/I701L). The localization of NFATC1 was visualized using an anti-Flag antibody. Nuclei of cells were visualized using the Hoechst dye (blue color). Wt and NFATC1 mutants localized to the cytoplasm in the absence of PPP3CA (red color). (Magnification ×40). B- Immunofluorescence of HeLa cells transfected with plasmids encoding for the Wt NFATC1 and NFATC1 Mutants (P66L, I701L, P66L/I701L) co-transfected with PP3CA. The localization of NFATC1 was visualized using an anti-Flag antibody (red color) while PP3CA was visualized using anti-HA antibody (green color). Nuclei of cells were visualized using Hoechst dye (blue color). Most of the cells co-transfected with the double NFATC1 mutant were retained in the cytoplasm around the nuclear membrane, whereas in the other cases, the protein was totally translocated to the nucleus. (Magnification ×40). Yellow arrows indicate cytoplasmic (peri-nuclear) staining, while red arrows indicate nuclear staining.
Techniques Used: Immunofluorescence, Transfection, Mutagenesis, Staining
Figure Legend Snippet: A- NFATC1 extracts from HEK 293 cells transfected with Wt NFATC1 and Mutants (P66L – I701L – P66L/I701L) were resolved on an SDS-PAGE prior to gel shift assays. Western blots showed equal amounts of expressed proteins as depicted by the anti-Flag antibody. (Ctrl refers to nuclear extracts from mock-transfected cells). B- EMSA was performed using equal amounts of the overexpressed NFATC1 proteins from HEK 293 cells transfected with Wt NFATC1 and NFATC1 mutants (P66L, I701L, P66L/I701L) and NFAT-consensus binding site as a probe. – ve sign indicates absence of nuclear extracts/* indicates NFATC1 monomer/** indicates NFATC1 Dimer/→ refers to the 32 P labeled free DNA probe. C- Quantification of the NFATC1 dimers in the EMSA using the TotalLab2010 software from Amersham shows a 30% decrease in DNA binding affinity of the single and double mutant as compared to the wild type NFATC1 protein.

Figure Legend Snippet: A- Wt NFATC1 or NFATC1 Mutants (P66L, I701L, P66L/I701L) were cotransfected with the human CCND1 promoter coupled luciferase reporter construct in the presence or absence of activated clacineurin (PPP3CA) in Hela cells. Six hours post transfection, media was changed and cells were harvested for luciferase assay after 36 hours. Relative luciferase activities are represented as fold activation. The data are the mean of three independent experiments done in duplicates +/− standard deviation. Significance (p<0.05) was assessed using the one-way Anova test. (* p<0.01, ** p<0.05) B- Wt NFATC1 or NFATC1 Mutants (P66L, I701L, P66L/I701L) were cotransfected with the human DEGS1 promoter coupled luciferase reporter construct in the presence or absence of activated clacineurin (PPP3CA) in Hela cells. Six hours post transfection, media was changed and cells were harvested for luciferase assay after 36 hours. Relative luciferase activities are represented as fold activation. The data are the mean of three independent experiments done in duplicates +/− standard deviation. Significance (p<0.05) was assessed using the one-way Anova test. (* p<0.01, ** p<0.05).
Techniques Used: Luciferase, Construct, Transfection, Activation Assay, Standard Deviation
Figure Legend Snippet: A- Wt NFATC1 or NFATC1 Mutants (P66L, I701L, P66L/I701L) were transfected with/without HAND2 and the DEGS1 promoter coupled to luciferase reporter construct in Hela cells. Six hours post transfection, media was changed and cells were harvested for luciferase assay after 36 hours. Relative luciferase activities are represented as fold activation. The data are the mean of three independent experiments done in duplicates +/− standard deviation. Wt NFATC1 and HAND2 synergistically activate DEGS1 promoter. This synergy was abrogated in all NFATC1 mutants. Significance (p<0.05) was assessed using the one-way Anova test. (* p<0.01, ** p<0.05) B- Wt NFATC1 or NFATC1 Mutants (P66L, I701L, P66L/I701L) were transfected with/without PPP3CA and with/without GATA5 to assess their combinatorial regulation of the DEGS1 promoter in HeLa cells. Six hours post transfection, media was changed and cells were harvested for luciferase assay after 36 hours. Relative luciferase activities are represented as fold activation. The data are the mean of three independent experiments done in duplicates +/− standard deviation. Wt NFATC1 cotransfected with GATA5 caused a synergistic activation of 35 fold, while transfection of Wt NFATC1 with PPP3CA and GATA5 caused even a stronger synergy reaching 68 fold. The synergestic activation was maintained in all mutants except for P66L/I701L double mutant where the synergy was totally lost. Significance (p<0.05) was assessed using the one-way Anova test. (* p<0.01, ** p<0.05).
