Description

This track shows expression of target RNA binding proteins (RBPs) as measured by RNA-binding protein immunoprecipitation-microarray profiling (RIP-chip) using different RIP antibodies in multiple cell lines. The RBP Assoc RNA view shows the genomic location of transcripts associated with the array probes. Data for this track was produced as part of the Encyclopedia of DNA Elements (ENCODE) Project,

In eukaryotic organisms gene regulatory networks require an additional level of coordination that links transcriptional and post-transcriptional processes. Messenger RNAs have traditionally been viewed as passive molecules in the pathway from transcription to translation. However, it is now clear that RNA-binding proteins play a major role in regulating multiple mRNAs in order to facilitate gene expression patterns. These tracks show the associated mRNAs that co-precipitate with the targeted RNA-binding proteins using RIP-Chip profiling.

Display Conventions and Configuration

This track is a multi-view composite track. For each view there are multiple subtracks that display individually in the browser. The subtracks within this track correspond to different antibodies/target proteins tested in different cell lines. This track is initially released with a single view:

RBP Assoc RNA
The RBP Assoc RNA view shows the genomic extent of the transcripts associated with the Affymetrix Exon Array probes, shaded according to score.
Instructions for configuring multi-view tracks are here.

Methods

RBP-mRNA complexes were purified from cells grown according to the approved ENCODE cell culture protocols . The associated messages were identified using Affymetrix Human Exon 1.0 ST Arrays. Measurements of expression at gene-level were extracted using Affymetrix tools, and were further processed to generate average fold-change and p-values for immunoprecipitation. Enriched regions were scored in the range ~100 to ~1000, and interrogated regions without significant signal were scored at 1. The signal value contains the minimum log2 fold-change, the p-value contains -log10 of the maximum p-value, and the q-value was left at the default of -1.

For additional methods detail, see Tenenbaum et al. 2002; Baroni et al. 2008; Penalva et al. 2004, below. Details of the RIP-chip analysis methods are available here.
