Transcription and translation coordinates, timing of expression, and function of latent, early lytic and delayed early lytic ORFs.

Transcription and translation coordinates for the primary viral ORFs were annotated from in silico predictions and/or by manually curating mRNA-seq and Ribo-seq data. Timing was determined according to the time of transcription. Functions were gathered from the literature. U: uORF in leader region; Str: Strand; TSS: transcription start site; N/A, not determined in silico or by manual annotation; Ann: Annotation; P: predicted; M: manual annotation; Sp. Var: ORF with splice variant, Alt. Start: ORF with alternative starts; Internal: ORF with internal ORFs; AS-ORF: Antisense ORFs; MHV68: Function annotated in MHV68.
