摘要: A comprehensive analysis of the structure neuronal nitric oxide synthase (nNOS; EC 1.14.13.39) mRNA species revealed NOS1 to be most structurally diverse human gene described date in terms promoter usage. Nine unique exon 1 variants are variously used for transcript initiation tissues, and each is expressed from a 5′-flanking region. The dependence on genomic regions control transcription cell-specific fashion burdens transcripts with complex 5′-mRNA leader sequences. Elaborate splicing patterns that involve alternatively spliced exons skipping have been superimposed this diversity. Highly structured nNOS 5′-untranslated regions, which profound effects translation both vitro cells, contain cis RNA elements modulate translational efficiency response changes cellular phenotype.
