Project description:Whi3 associated mRNAs were identified by immunoprecipitation of TAP-tagged Whi3 followed by microarray analysis RNA IP of Whi3-TAP and Whi3-dRRM-TAP with total RNA as reference. Each sample has 2 replicates
Project description:BRAT-associated mRNAs and PUM-associated mRNAs were identified in early Drosophila embryos by RNA co-immunoprecipitation of the endogenous proteins using synthetic antibodies, followed by microarray analysis (RIP-Chip).
Project description:RIN-associated mRNAs were identified in early Drosophila embryos by RNA co-immunoprecipitation of the endogenous protein using a synthetic antibody (anti-RIN D072), followed by microarray analysis (RIP-Chip).
Project description:In vivo cross-linking and ribonucleoprotein-immunopurification experiments followed by microarray analysis of bound RNAs (X-RIP-chip). Cells expressing recombinant tandem-affinity purification (TAP)-tagged Trf4 protein were cross-linked with formaldehyde, and Trf4-containing ribonucleoprotein complexes were recovered by affinity selection on IgG-coupled beads (see linked protocol). As a control for non-specifically enriched RNAs, the same experiment was done with untagged WT cells and with cells expressing Fpr1-TAP, a peptidyl-prolyl-cis-trans-isomerase not expected to bind RNA. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Antigenic peptide used in IP: Protein A derivative

Project description:Staufen-associated mRNAs were identified in early Drosophila embryos by RNA-co-immunoprecipitation followed by microarray analysis (RIP-Chip), using two complementary approaches: RIP-Chip from wild-type embryos using a synthetic anti-Staufen antibody, and RIP-Chip from transgenic GFP-Staufen-expressing embryos using an anti-GFP antibody. Genome-wide transcript expression in whole embryos was also assessed for the wild-type and GFP-Staufen lines.
Project description:FOG-1/CPEB and FOG-3/Tob are the terminal regulators of the sex determination in C. elegans germ cells. CPEB and Tob proteins are both translational regulators. To investigate how FOG-1 and FOG-3 regulate germ cell sex determination we sought to identify the target mRNAs. We used transgenic epitope tagged animals (3xMyc::FOG-1 and FOG-3::3xFLAG). To identify the mRNA targets of FOG-1/CPEB and FOG-3/Tob on a genome wide scale we used RNA immunoprecipitation followed by microarray analysis. We found 81 putative mRNA targets of FOG-1 and 722 putative targets of FOG-3. 76 target mRNAs were common to both FOG-1 and FOG-3.
Project description:mRNA poly(A) tail plays a key role in post-transcriptional regulation of gene expression, including mRNA decay and translation. Deadenylation is a rate-limiting step in mRNA decay, which is catalyzed by the CCR4-NOT complex. To identify mRNAs associated with the CCR4-NOT complex, we have done RIP-CHIP (RNA-immunoprecipitation followed by DNA microarray) using primary hepatocytes from CNOT6L wild-type and knockout mice.
Project description:BRAT-associated mRNAs and PUM-associated mRNAs were identified in early Drosophila embryos by RNA co-immunoprecipitation of the endogenous proteins using synthetic antibodies, followed by microarray analysis (RIP-Chip). Nine RNA co-immunoprecipitations were performed. This includes 3 biological replicates each of 1) anti-BRAT RNA co-immunoprecipitations from wild-type 0-3 hour embryos, 2) anti-PUM RNA co-immunoprecipitations from wild-type 0-3 hour embryos, and 3) control antibody RNA co-immunoprecipitations from wild-type 0-3 hour embryos. BRAT samples and PUM samples were each normalized separately with the control samples, for a total of 12 processed samples (3 BRAT with 3 control normalized together, and 3 PUM with 3 control normalized together) from the 9 RNA co-immunoprecipitations.
Project description:A tagged ectopic version of the ELAV-like protein Tb927.8.6650 of T. brucei was expressed in stable cell lines and pulled down. Co-purifying transcripts were analyzed by sequencing to identify RNAs associated with Tb927.8.6650. Stable procyclic form cell lines expressing tetracycline-inducible TAP-tagged Tb927.8.6650 were created. Cells were harvested 48h after tet-induction, followed by tandem affinity purification of Tb927.8.6650, extraction of co-purified RNA, and sequencing.
