Figure 3A,B, No difference in voltage dependent Ca2+-currents (A) and fractional activation of ICa-channels (B) between OtofI515T/I515T IHCs (n=16) and IHCs of Otof+/+ littermates (n=13). C, Exocytosis was recorded by measures of changes in membrane capacitance (ΔCm, lower panel) in response to depolarization (left, 20ms; right, 100ms) to the voltage where maximum Ca2+-currents were elicited (upper panel), typically -14mV. D, Upper panel, while for stimuli up to 20ms exocytosis from OtofI515T/I515T (n=13) and Otof+/+ (n=11) IHCs was similar, sustained exocytosis, representing most likely the release of replenished vesicles, was significantly reduced in OtofI515T/I515T IHCs (t-test). Lower panel, Ca2+-current integrals were of similar size. E, Flash photolysis of caged Ca2+ elicited a smaller exocytic response in OtofI515T/I515T IHCs. F, The kinetics of the fast component from E was comparable between OtofI515T/I515T IHCs and Otof+/+ littermates (b). Open circles represent previously published data on IHCs of hearing wild-type mice (a; Beutner et al, 2001; Pangrsic et al, 2010).
Figure 3A Combined immunofluorescence and DNA FISH analysis of the kinetochore inner plate/centromere formation in Miwi heterozygous (Miwi+/-) and knockout (Miwi-/-) spermatocytes at diakinesis/metaphase I. For slicer activity-deficient mutant spermatocytes (Miwi-/ADH), the images are presented in Fig EV1A. Chromosomes were stained with anti-centromere protein antibody (CREST, purple signal), indicating the kinetochore inner plate/centromere. Major satellite DNA regions were detected using an antisense probe (red signal) which revealed the specific localization of pericentromeres in chromosomes. Nuclear DNA was stained by DAPI (blue). Scale bars represent 2 µm. B Left panel: illustration of kinetochore configurations in meiotic metaphase I. The kinetochores of sister chromatids cohere to form a single microtubule-binding interface. The inner-outer kinetochore axis connects the pericentric chromatin to the spindle microtubule. CREST (centromere protein) and BUBR1 (budding uninhibited by benzimidazole-related 1) served as markers for the inner and outer regions of the kinetochore, respectively. A major satellite DNA (Maj sat DNA) probe was used to detect the pericentric chromatin. Right panel: categories of inner kinetochore configurations from A. Right panels: Inner kinetochore configurations in MI were classified as overlapping (two sister kinetochores which overlap by more than their individual radii, also see yellow arrow in A), adjacent (two sister kinetochores which overlap by less than 100% of their individual radii, also see magenta arrow in A) or separated (two sister kinetochores without overlapping, also see light blue arrow in A) kinetochores. The scale bar represents 1 µm.D Combined immunofluorescence and DNA FISH analysis of kinetochore inner and outer plate formation in Miwi heterozygous (Miwi+/-) and knockout (Miwi-/-) at diakinesis/metaphase I. For slicer activity-deficient mutant spermatocytes (Miwi-/ADH), the images are presented in Fig EV1B. Chromosomes were stained with anti-BUBR1 (green) and anti-centromere-protein (CREST, purple) antibodies to mark the kinetochore outer and inner plate, respectively. In addition, major satellite DNA regions were further detected using an antisense probe (red signal). Nuclear DNA was stained by DAPI (blue). O-O kinetochore pairs: yellow arrow; S-S, magenta arrow; O-S, light blue arrow; and S-O, light green arrow. Scale bars represent 2 µm.
ΔPrPs have a GPI-anchor attached.Figure 4A. ΔPrPs are substantially soluble in detergent without GdnHCl denaturation. Immunoblots probed with mAbs 3F4 (left) or 4H11 (right, membrane re-probed) showing ΔPrPs and endogenous PrP in detergent and aqueous phases of TX114 lysates prepared from N2a cells transfected with Δ159 or Δ159-175. Det denotes detergent phase, Aq aqueous phase. B. ΔPrPs are highly hydrophobic after denaturation with GdnHCl. Representative immunoblot of TX114-treated lysates after denaturation with 3 M GdnHCl and developed with mAb 3F4 showing Δ159 and Δ159-175 almost exclusively in detergent phase (lanes 1-4). PIPLC treatment (+, even lanes) was done after denaturation with GdnHCl or not (−, uneven lanes). PIPLC treatment did not significantly influence ΔPrP partitioning under these conditions. C. Hydrophobicity of ΔPrPs combined with sensitivity to PIPLC digestion. After further diluting out GdnHCl by phase-separation and removal of the aqueous phase containing GdnHCl, PIPLC was able to digest ΔPrPs. Left two panels (upper mAb 3F4, lower 4H11) are shorter expositions, right panels longer expositions to show also difference in PrP levels in the detergent phase. Under these conditions a substantial reduction of ΔPrPs in the detergent phase was achieved by PIPLC digestion (e.g. upper-left panel, lanes 1, 3 vs. 2, 4). Migration of ΔPrPs in the aqueous phase of PIPLC-digested samples was slightly slower than that of PIPLC-undigested samples (−) (upper-right panel, lane 9 vs. 10).

Analysis of the apg9ts strain indicates Apg9p is directly required for the vesicle formation step.Figure 10Analysis of the apg9ts strain indicates Apg9p is directly required for the vesicle formation step. A, The nature of prAPI binding and pelleting in the apg9ts strain. Spheroplasts of apg9ts were labeled for 10 min and chased for 30 min at 38°C. The spheroplasts were osmotically lysed in a buffer containing no salt (20 mM Pipes, pH 6.8) or a physiological concentration of salt (100 mM KOAc, 50 mM KCl, 5 mM MgCl2, 20 mM Pipes, pH 6.8) and pelleted at 5,000 g. All samples were immunoprecipitated with antiserum to API and the cytosolic marker PGK. apg9ts retains the salt dependent binding and pelleting of prAPI. B, prAPI in the apg9ts strain accumulates in both a membrane-associated state and a large pelletable complex. Spheroplasts of apg9ts and ypt7Δ were labeled for 10 min and chased for 30 min at 38°C. The labeled spheroplasts were then osmotically lysed and separated into supernatant (S) and pellet (P) fractions by centrifugation at 5,000 g for 5 min. An aliquot was removed for the total lysate control (T). The pellet fraction (P) was resuspended in 15% Ficoll-400 in gradient buffer (20 mM Pipes, 5 mM MgCl2, complete EDTA-free protease inhibitor cocktail) in the presence or absence of Triton X-100 and overlaid with 13 and 2% Ficoll-400 in gradient buffer. The step gradients were centrifuged at 13,000 g for 10 min. Membrane-containing float (F), nonfloat (NF), and pellet (P2) fractions were immunoprecipitated with antiserum to API as described in Materials and Methods. The position of prAPI is indicated. C, prAPI in the apg9ts strain is protease accessible. Spheroplasts isolated from apg9ts and ypt7Δ cells were pulse-labeled for 10 min and chased for 30 min at 38°C. The labeled spheroplasts were then osmotically lysed and separated into low-speed supernatant (S) and pellet (P) fractions after a 5,000 g centrifugation step. The pellet fractions were subjected to protease treatment in the absence or presence of 0.2% Triton X-100 as described in Materials and Methods. The resulting samples were immunoprecipitated with antiserum to API and PGK. The immunoprecipitated bands were quantified by a Molecular Dynamics STORM PhosphorImager. The percent protease-protected prAPI was determined by dividing the value for prAPI in the protease-treated sample by the value for total prAPI before protease treatment. The percent PGK was determined by dividing the supernatant (S) or pellet (P) value over the sum of the S and P values.
