AIR 2-is localized in the cohesion sites of homologous chromatids in meiosis I of wild typ-e C. elegans. Concurrently, the AIR 2 substrate histone H3 was phosphorylated within the entire period of the chromosomes. Our results show that CDC 48s play an essential role in proper Avagacestat gamma-secretase inhibitor chromosome segregation all through meiosis in C. elegans. In this study, we used C. elegans N2 worms because the wild typ-e strain. Mutant worms AZ212 unc 119 ruIs, VC280 air 2 /okIs59, and HT1593 unc 119 were given by the Caenorhabditis Genetics Center, and FX301 gsp 2 /hT2 and FX544 cdc48. 1 were given by Dr. S. Mitani. XA7200 unc 119 qaIs7200 and XA7203 unc 119, cdc 4-8. 1 qaIs7201 have now been described previously. We produced ranges XA7210 unc 1-19, cdc 4-8. 1 ruIs and XA7215 Pgsp 2 HA GSP 2 Cbr unc 1-19 ]. XA7210 was created by transferring the cdc 48. 1 removal mutation in-to AZ212. Deletion strains were confirmed by PCR. XA7215 was generated as follows. The expression plasmid for FLAG AIR 2, HA GSP 2, and wild type UNC 1-19 based on Caenorhabditis briggsae was filled and created into HT1593 using the Bio-rad Biolistic PDS 1000/He particle delivery system as described previously. Unc saved viruses were obtained, and FLAG AIR 2 and HA GSP Infectious causes of cancer 2 expressing transgenic lines were screened by western blotting. Finally, the air 2 and gsp 2 deletion mutations were transferred by mating. The FLAG AIR 2 and HA GSP 2 fusion proteins were considered to be practical, considering that the homozygotes were sensible. The typical types of handling and culturing C. elegans have now been described elsewhere. Nematode experiments were performed at 20 C un-less otherwise specified. To make RNA disturbance hedgehog pathway inhibitor plasmids, full-length cDNA fragments of air 2, gsp 1, and gsp 2 were cloned into the pLITMUS28 plasmid. RNAi plasmids for cdc 4-8. 1 and cdc 4-8. 2 were described previously. Therefore, we knocked down AIR 2, GSP 1, GSP 2, CDC 4-8. 1, and CDC 4-8. 2-using the perfect feeding RNAi process with RNAi plasmids. Alternately, we prepared dsRNAs for them in-vitro and knocked down their expression utilizing a soaking RNAi approach. We made a mouse monoclonal antibody against AIR 2, the details that will be described elsewhere. These immunofluorescence studies were performed at 25 C unless otherwise specified. Germlines were dissected on the poly L lysinecoated glass slide, fixed with 2% paraformaldehyde in phosphatebuffered saline containing 0. 1000 Tween20 for 1 h, and incubated in pre cold a large number of dimethylformamide for 10 min. Fixed samples were rehydrated with PBSTw for 30 min and blocked with three times bovine serum albumin in PBSTw for 1 h. The slides were incubated with antibody diluted in PBS containing one of the BSA, 0. Five full minutes Triton X 100, and 0. 0-50 sodium azide for 16 h at 4 C.
