Figure Legend Snippet: (A) Vectors to append homology regions upstream and downstream of the MS2V6 repeats; vc591 (24x MS2V6) and vc592 (12x MS2V6) are slightly modified versions of Addgene plasmids # 104393 and # 104392 (Tutucci et al., Nat Methods 2017). An EcoRI site was added downstream of the MS2V6 repeats. Homology regions can be integrated at the BamHI, EcoRI, and XhoI sites. (B,C,D) Strategies to integrate the 12-24x MS2V6 repeats into the genome: (B) CRISPR/Cas9-facilitated integration without resistance gene; (C) replacement of a counterselectable cassette, e.g. when working with a non-essential gene; (D) integration using the kanMX resistance gene present on the vector.
Techniques Used: Modification, CRISPR, Plasmid Preparation
Figure Legend Snippet: (A) The mad2 gene was tagged in the 3’UTR with 24x MS2V6, and MCP-tdSG was expressed from different promoters. (B) Short kymographs from live-cell imaging; longer sequences are shown in Fig. S3. For each MCP-tdSG construct, a strain without integration of MS2 repeats is shown as control. Far left: strain expressing mad2 -24xMS2, but no MCP-tdSG. Images are maximum intensity projections of the Z-stack. Note the different scaling setting for P.cdc2.short-MCP-tdSG. (C) Quantification of the maximum spot intensity over maximum background intensity. Two replicates per strain, 56-162 spots per replicate. Points: individual spots; box plot: summary statistics (center line, median; box boundaries, 1st and 3rd quartiles). (D) The cdc13 gene was internally tagged with circularly permuted superfolder GFP (sfGFPcp) and 12x or 24x MS2V6 cassettes were inserted in the 3’UTR. The construct was expressed under endogenous cdc13 regulatory sequences (promoter, terminator) from the leu1 locus. MCP-tdSG was expressed from the mad3 promoter. (E) Schematic illustrating Cdc13 protein localization. Cdc13 accumulates during interphase and is strongly enriched in the nucleus. Cdc13 localizes to spindle pole bodies and the spindle during early mitosis and becomes degraded at the metaphase-to-anaphase transition. (F,G) Kymographs from live-cell imaging of cells undergoing mitosis; cdc13 -sfGFP tagged with either 24x MS2V6 (F) or 12x MS2V6 (G). A strain without MS2 repeats is shown as control. Images were recorded every 5 sec (F) or 12 sec (G); every second image (every 10 sec, F) or every 10 th image (every 2 min, G) is shown. Images are maximum intensity projections of the Z-stack. (H) Similar to (G), but showing an interphase cell; loss of the nuclear sfGFPcp signal is due to photobleaching, not degradation.
