Descriptor English: Ribosome Shunting
Descriptor Spanish: Derivación del Ribosomas
Descriptor derivación ribosómica
Scope note: Mecanismos víricos de programación traduccional en los que los ribosomas alcanzan el codón de inicio saltándose u omitiendo grandes segmentos de la región 5' UTR del ARN VÍRICO. La derivación ribosómica permite en la maquinaria traduccional del huésped su intervención en transcritos policistrónicos similares al DESFASE DEL MARCO DE LECTURA RIBOSÓMICO y el uso de SITIOS DE ENTRADA INTERNOS AL RIBOSOMA.

Scope note: Viral mechanisms of translational programming in which ribosomes reach the start codon bypassing or shunting over large segments of the 5′ UTR of VIRAL RNA. Ribosome shunting allows host translational machinery to engage polycistronic transcripts similar to RIBOSOMAL FRAMESHIFTING, and use of INTERNAL RIBOSOME ENTRY SITES.
