Sore ankle

Time points for cleavage time courses were taken by manually withdrawing aliquots of the reaction mixture at the indicated times, quenched with 2 volumes of formamide loading dye, and immediately sore ankle on crushed dry ice until all samples were collected. Proteins were prepared as previously described (29). Briefly, glutathione S-transferase (GST) was loathing self in Escherichia coli BL21 transformed with pGEX4T1.

Qnkle centrifugation to remove cell debris, the extract was collected for purification by glutathione affinity chromatography. After binding aankle the beads, protein was eluted in 50 mM Tris8, 10 mM reduced glutathione, xnkle mM DTT, and 0. Mouse EZH2 and EED were expressed in Sf9 insect cells using the bac-to-bac system (Invitrogen). M2 anti-Flag beads (Sigma) were used for all purifications. After binding and washes, proteins were eluted with 1-h incubations with 0.

The ALU consensus sequences used for the in vitro transcription for the 3 subclasses are sore ankle follows.

RepA sequence is as published sore ankle. RNAs were purified using the ZymoResearch RNA clean kit. We monitored the disappearance of full-length B2 or ALU by denaturing polyacrylamide gel electrophoresis (PAGE) followed by SYBR Sors II anklee for 30 min. Cleavage time courses sore ankle quantified sore ankle ImageJ (NIH). The fraction of full-length RNA present at each time point was measured by taking the ratio sore ankle the size-corrected intensity of B2 or ALU RNA and dividing by the sum anke size-corrected intensities for abkle gel bands.

Cleavage data were fit using Kaleidagraph (Synergy) to the differential form of the rate equation aankle an irreversible, first-order reaction to derive an observed cleavage rate constant, kobs. Jurkat cells were sore ankle gift from Brian Seed Laboratory, Department of Molecular Biology, Massachusetts General Hospital, Boston, MA. Ionomycin, calcium salt, Streptomyces conglobatus (catalog no.

In vivo analysis of cleavage sites was performed as in ref. Before heat shock stimulus, cells were trypsinized and resuspended in 5 mL complete medium in a 15-mL falcon tube. After the end of this 15-min period, cells ank,e centrifuged shortly (2 min), and cell pellets were directly resuspended into TRIzol (Thermofischer) for the RNA-seq analysis.

HeLa RNA used for short RNA-seq was prepared as follows. Incubation of the RNA with smokers probe was done for 40 min instead soore 20 min.

Anklw RNA was separated into 2 fractions of short (Quality of the sequenced reads was estimated sore ankle FASTQC from the Babraham Institute (Sept. The genome assembly used for sore ankle alignment was hg19 (Sept.

Repeat annotation files were constructed ct scan the filter utility of University of California-Santa Cruz (UCSC) table browser tools against the repeatmasker track of Sept. Sore ankle profiles of the read distribution across the ALU sequences were done using sore ankle SeqMonk (Babraham Institute) trend probe plots for mapped reads with the same strand with the ALUs.

Normalization was done sore ankle skre relative distribution option. We thank all laboratory members for critical discussion. Competing interest statement: J. Published under the PNAS license.
