The following table summarizes the expression values of all known features of the gene 'SRP54' in each library. Known features (i.e. those that correspond to one or more EnsEMBL transcripts) are included regardless of their expression level. Novel features are only reported in this table if they are expressed above the level of intergenic background noise. The 'FID' column reports the unique Feature ID for the gene, transcript, exon region, exon junction, etc. The 'Name' column reports the Feature Name for the feature (e.g. E5a_E6a is the name of an exon junction corresponding to the connection of exons 5 and 6). The 'Type' column reports the type of the feature and may be one of the following: Gene, Transcript, Exon Region, Known Junction, Novel Junction, Known Boundary, Novel Boundary, Silent or Active Intronic Regions, and Silent or Active Intergenic Regions (see our manuscript for more details). The 'Base Count' column reports the number of nucleotide bases for the feature followed by the percent of these that do NOT correspond to repeats and the percent that are known to be protein coding in one or more EnsEMBL transcripts. The 'Supporting ESTs/mRNAs' column reports the number of ESTs and mRNAs that when aligned to the human genome support the expression of a feature (i.e. the sequence alignment coordinates match an exon junction or boundaries of an exon, retained intron, etc.). The 'Conserved Species' column reports the number of 'other' species for which there was at least 1 supporting EST/mRNA alignment. Finally, the remaining columns report the log2 expression value for each feature in each library. Bold values indicate expression above background. Each expression value is also a hyperlink to a view of the feature's corresponding genomic region in the UCSC genome browser. Expression data will automatically be loaded as custom GFF and wiggle tracks.
