I am working on a project in which I need to compute several parameters (such GC content and length) of 5'UTR and 3'UTR sequences of Saccharomyces cerevisiae yeast genes.
The problem is finding a proper annotation for these regions in yeast. I have tried with BiomaRt and these sequences are not available for yeast. I have also tried with UCSC table browser to obtain a BED file with 5'UTR or 3'UTR sequences but it is returning only coordinates of tRNAs, pseudogenes, ncRNAs.
In summary, is there a straight-forward way to obtain an annotation for 5'UTR and 3'UTR regions in Saccharomyces cerevisiae yeast?
