Is there a trustworthy and so-called comprehensive annotation for drosophila melanogaster of all genomic regions in order to construct a TSS (transcription start site) database? Is it UCSC (by quering), modENCODE, flybase or ensembl that i should search for it? I am looking for something like the Gencode annotation for human/mouse preferably in gtf format (gencode.v19.annotation.gtf) which looks like this:

##description: evidence-based annotation of the human genome (GRCh37), version 19 (Ensembl 74)
##provider: GENCODE
##contact: gencode@sanger.ac.uk
##format: gtf
