Experimental details: 11 Immunolocalization of CaMKIIdelta and phospho-CamKIIdelta at E11.5 in TgPCP4 and Ts1Cje. A,B : Immunohistochemistry of CaMKIIdelta (A) and phospho-CaMKIIdelta (B) on close sagittal sections of E11.5 wt embryos showing the localization of CaMKIIdelta in the nervous system at the pial surface of the neuroepithelium in the telencephalon (Tel), diencephalon (Di), mesencephalon (Mes), and rhombencephalon (Rh) and spinal cord (sp) and in the dorsal root ganglia (drg). Phospho-CaMKIIdelta showed a close pattern to CaMKIIdelta with less intense signals. The p-CaMKIIdelta signal is more intense at the level of the pial surface. C-T : Immunohistochemistry of phospho-CaMKIIdelta (p-CaMKIIdelta, green) and pcp4 (red) in (C-K) postmitotic neurons of the rhombencephalon (r6 level) and in (L-T) dorsal root ganglia in wt, TgPCP4, and Ts1Cje embryos corresponding to boxed area in B. Immunolocalization of p-CaMKIIdelta was enhanced in the rhombencephalon (D,E, arrows) and in the anterior roots of ganglia (M,N, arrows) in TgPCP4 and Ts1Cje compared with wt (C,L). U-X : Colocalization of CaMKIIdelta (green) and pcp4 (red) at E11.5 in regions corresponding to the boxed area in A. Note the more intense colabeling of CaMKIIdelta and pcp4 in the TgPCP4 postmitotic cells (pm) of the rhombencephalon (r5-r6 level) indicated by arrows (V) and dorsal root ganglia (DRG) (X). Scale bar = 500 mum in A,B; 50 mum in C-X.

Experimental details: Figure 6 Gender-associated changes in CaMKP and in CaMKII activation in cardiac subcelullar fractions 30 days after TAC. ( A ) Representative immunoblots of Oct1, GAPDH, CaMKP, CaMKII (phospho-Trh286 CamKII and total CaMKII) and HDAC4 (phospho-HDAC4 (Ser246)/HDAC5 (Ser259)/HDAC7 (Ser155) and total HDAC) in cardiac subcellular fractions (nuclear (n) and cytoplasmic (c)) of mouse hearts of both genders 30 days after sham-operation (Sham) or thoracic aortic constriction (TAC). In histograms, blue bars indicate male mice (light blue bar: M Sham; dark blue bar: M TAC), and red bars indicate female mice (light red bar: F Sham; dark red bar: F TAC). ( B - C ) Quantification of CaMKP protein level in LV nuclear ( B ) or cytoplasmic ( C ) extracts reveals a marked gender-dependent up-regulation of CaMKP expression in LV samples after TAC. CaMKP protein levels are increased in both nuclear and cytoplasmic extracts in male mice only. ( D - E ) Phosphorylation status of CaMKII in LV nuclear ( D ) and cytoplasmic ( E ) extracts: phospho-Thr286 CaMKII (yellow bar); total CaMKII (green bar); pCaMKII/tCaMKII ratio (red bar). CaMKP and CaMKII protein levels are expressed as fold increases in TAC mice relative to their respective sham groups. N = 4-8 mice per group. *p

Experimental details: Figure 6 Effects of hyperaldosteronism and/or hypoestrogenism on activation of Ca 2+ -signaling pathway (Cn/ NFAT /Ca MKII ,) proteins in wild type ( WT ) or aldostereone synthase overexpressing ( AS ) mouse hearts. (A) shows representative immunoblots of activation of calcium-calmodulin-dependent kinase II (Ca MKII ): its oxidation (Ox-Ca MKII ) or its phosphorylation (phospho-Thr 286 ), and calcineurin (Cn), and nuclear factor of activated T-cells ( NFAT c4) and its phosphorylation (phospho-Ser 168/170 ), and its inhibitor, calcipressin ( MCIP ). (B-G) illustrated their respective quantifications, Ca MKII activity calculated as the ratio of Ox-Ca MKII to Ca MKII , and/or p-Ca MKII to Ca MKII . The ratio of p- NFATC 4 to NFATC 4 indirectly reflected Cn activity. Ca MKII and pan Cn and MCIP protein expression level normalized to that of GAPDH .

Experimental details: Fig. 1 GluN2A(N615S) containing NMDAR expression in vitro and in vivo. a The position of N615 in the membrane segment M2 is depicted together with the three channel-forming trans-membrane segments M1, 3, and 4. b In HEK293 cells, recombinantly expressed GluN1/GluN2A and GluN1/GluN2A(N615S) channels were activated by fast glutamate application (1 mM; in the continuous presence of the co-agonist glycine, 10 uM) at holding potentials from -100 to +40 mV in different extracellular Mg 2+ concentrations. NMDAR-mediated peak currents were normalized to those obtained at +40 mV. Data points represent mean +- SEM for n = 4-7 different HEK293 cells. Representative current traces evoked in 0 mM Mg 2+ at - 60 mV, with 20 and 600 ms applications, are shown below the IV plots and were used to determine the current kinetics (Supplementary Table 1 ). c Schematic view of the A to G replacement in exon 10 of the mouse Grin2a gene. d Reverse transcription PCR (RT-PCR)-sequence analyses of total brain mRNA show the A-to-G mutation in pos. 0 and two diagnostic silent mutations at pos. -11 and -14 in the pore loop encoding gene segment in Grin2a +/+ , Grin2a S/S , Grin2a +/S mice. In Grin2a +/S mice, the overlay of two different colored ""nucleotide"" peaks, at position 0, -11, and -14 indicate equimolar amounts of mRNA from the Grin2a + and the targeted Grin2a S alleles. e Immunoblots of forebrain protein lysates of 4-week-old mice (Supplementary Fig. 2 ) indicate no genotype-specific differences
