Low-level expression vector pGBT9 due to the fact its high level expression was toxic in yeast. One-hybrid reporter assays were performed primarily as described previouslyEmbryo analysesThe time of pregnancies was defined as E0.five on the morning vaginal plugs have been observed in Asciz+/2 intercrosses. EmbryosPLoS Genetics | plosgenetics.orgASCIZ Regulates Pulmonary Organogenesisfor two-hybrid assays in our laboratory [55,56] except that plates have been supplemented with leucine. For mammalian dual luciferase reporter assays, the 667-residue ASCIZ isoform was cloned into pCDNA3-Gal4DBD for transient transfection of U2OS cells with equal amounts of the reporter vectors pFR-Luc and pRL-CMV for use using the Dual-Luciferase Reporter Assay kit (Promega) in line with the manufacturer’s instructions and measurement of luminescence working with a Polarstar Optima (BMG Labtechnologies).KU55933 (ATMi; with pretreatment for 2 hours before MMS addition) as indicated.

(A) U2OS cells have been treated with GL2 manage or Asciz siRNA si579 [15] and treated with 0.02 MMS for the indicated instances. (B) U2OS cells have been treated with GL2 handle or two separate Asciz siRNAs as described and lysed 1 hour following two Gy gamma irradiation, and blotted together with the indicated antibodies. The arrow points for the position of ATM in the pS1981-ATM blot, the more abundant upper band represents cross-reactivity on the antibody with near-identical phosphorylation sites inside a larger protein, possibly 53BP1. Blots above and below the lines are from separate experiments. Note that an older ASCIZ antibody batch was employed for this experiment that crossreacts using a ,100 kDa band just beneath ASCIZ not observed using the new antibody batch within the other figures.

E12.5 WT and Asciz2/Supporting InformationFigure S1 Instability of the residual Asciz mRNA in Asciz null embryos. Northern blot analysis of E14.five head extracts of four separate WT and Asciz null embryos probed with exon C- or Dspecific probes and Gapdh as loading manage. Markers on the left indicate (from leading to bottom) 10 kb, 8 kb, 6 kb, four kb and three kb. Note that 2 bands of ,five.five kb and ,three kb are detected with both Asciz probes in the WT, indicating alternative splicing. The similar size on the most important band with the exon D-deleted transcript towards the 5.5 kb WT mRNA is most likely due to read-through from the exon C splice donor junction (within the absence of an exon D splice acceptor) to a poly-adenylation signal downstream in the loxP site. Image quant phosphoimager density units for these bands are: WT, 2154561282; KO, 298661032.
