LAS PROTEINAS ARGONAUTA PRODUCEN LA INTERFERENCIA RNA-RNA RESPONSABLE DEL SILENCIAMIENTO GENICO EN EUCARIOTAS, AUNQUE MUCHAS ARQUEAS Y ALGUNAS BACTERIAS TAMBIEN CODIFICAN PROTEINAS DE LA FAMILIA ARGONAUTA. LA PROTEINA THAGO DE THERMUS THERMOPHILUS ( HOMOLOGA DE LA PROTEINA AGO2 HUMANA) PRESENTA LA INUSUAL CAPACIDAD DE CORTAR DNA COMPLEMENTARIO A GUIAS DE SSDNA, LO QUE CONSTITUYE UN NOVEDOSO SISTEMA DE INTERFERENCIA DNA-DNA. DATOS PREVIOS DEL LABORATORIO SOLICITANTE MUESTRAN QUE THAGO ACTUA COMO BARRERA DE INMUNIDAD INNATA FRENTE A DNA EXOGENO, DESTRUYENDO DE FORMA EFICAZ LA MAYOR PARTE (90%) DE LAS MOLECULAS DE DNA QUE ENTRAN EN LA CELULA POR TRANSFORMACION, PERO SIN ACTUAR SOBRE EL MISMO DNA CUANDO ESTE ES TRANSFERIDO DESDE OTRA BACTERIA DEL MISMO GENERO, LO QUE SUGIERE QUE LA ACTIVIDAD DE THAGO ESTA SOMETIDA A REGULACION EN LA CELULA. POR OTRA PARTE, LA CAPACIDAD DE CORTE DIRIGIDO POR SSDNA DE THAGO CONSTITUYE UNA PROPIEDAD DE EXTRAORDINARIO POTENCIAL DE APLICACION EN EDICION DE GENOMAS, SIMILAR EN SU FUNCIONAMIENTO PERO CON POTENCIALES VENTAJAS SOBRE EL SISTEMA CRISPR/CAS9. DE HECHO, EN UN PROYECTO EXPLORA FINALIZADO EN 2015 OBSERVAMOS QUE LA EXPRESION TRANSITORIA DE THAGO EN CELULAS DE RATON TRANSFECTADAS CON OLIGONUCLEOTIDOS GUIA ESPECIFICOS PRODUCIA EL APAGADO EN LA EXPRESION DE GFP DESDE UN PLASMIDO. EN EL PROYECTO QUE SE SOLICITA PRETENDEMOS PROFUNDIZAR EN LOS MECANISMOS QUE LE PERMITEN A THAGO DISTINGUIR ENTRE DNA ADQUIRIDO POR TRANSFORMACION O TRANSFERIDO DE OTRAS CELULAS CON EL FIN DE ENTENDER Y OPTIMIZAR SU FUNCIONAMIENTO DE CARA A SU APLICACION COMO HERRAMIENTA EN LA EDICION DE GENOMAS._x000D_ COMO PASO PREVIO A CUALQUIER PROCESO DE OPTIMIZACION DE LA PROTEINA, EL PRIMER OBJETIVO PROPUESTO TITULADO ¿IDENTIFICACION DE LOS COMPONENTES Y LOS MECANISMOS DE ACTIVACION/DESACTIVACION IMPLICADOS EN LA RESPUESTA DE INTERFERENCIA DNA-DNA MEDIADA POR THAGO¿, SERA ABORDADO MEDIANTE UNA COMBINACION DE TECNICAS BIOQUIMICAS, PROTEOMICAS Y GENETICAS PARA IDENTIFICAR POSIBLES MODIFICACIONES COVALENTES E INTERACCIONES CON OTRAS PROTEINAS NECESARIAS PARA LA INTERFERENCIA. EN EL SEGUNDO OBJETIVO ¿UTILIZACION DE PROTEINAS PAGO COMO HERRAMIENTAS PARA LA MODIFICACION DE DNA¿, SE ABORDARA LA MODIFICACION DE THAGO TANTO FOCALIZADA EN BASE A LOS DATOS OBTENIDOS EN EL PRIMER OBJETIVO, COMO AL AZAR, MEDIANTE EVOLUCION DIRIGIDA IN VITRO. LAS VARIANTES MAS EFICIENTES EN ENSAYOS DE CORTE DIRIGIDOS POR GUIA SERAN UTILIZADAS IN VITRO EN PROCESOS DE MODIFICACION DE DNA COMO ENZIMA DE RESTRICCION PROGRAMABLE, Y APLICADAS DIRECTAMENTE IN VIVO PARA LA EDICION DE GENOMAS DE PROCARIOTAS Y EUCARIOTAS. EN EL CASO DE LOS GENOMAS DE EUCARIOTAS, LA ADICION DE DE SEÑALES DE LOCALIZACION NUCLEAR A ESTAS VARIANTES MEJORADAS PERMITIRIA LA TRANSFECCION DIRECTA DE LA PROTEINA YA UNIDA A GUIAS DE SSDNA, EVITANDO EL RIESGO DE INCORPORACION ACCIDENTAL DE DNA EXOGENO EN EL GENOMA ASOCIADO A LAS TECNICAS CRISPR/CAS9 ACTUALES.
