tokens: Sequence analysis revealed significant differences between the 5 ' region of the beta subunit gene and the corresponding regions of the homologous GlyR alpha subunit genes ; it also identified a novel exon ( exon 0 ) that encodes most of the 5 ' - untranslated portion of the GlyR beta mRNA .
