ENSEMBL browser. The ContigView page of the Ensembl browser representing the SPAG4 gene locus on chromosome 20 within the Encode region ENr333. (a) The green transcript represents the CCDS coding region agreed on by the CCDS consortium. (b) The blue transcripts are the Vega transcripts, which are manually annotated by the HAVANA group and are a mixture of coding (solid blues) and noncoding (blue outline) transcripts. (c) Finally, the gold transcript represents the coding transcript on which the HAVANA and Ensembl annotations agree.
