1. Informazioni di base Interazioni proteina-proteina (PPI) sono i mattoni fondamentali coinvolti nel governare tutti i processi cellulari. Di conseguenza, è essenziale che tutte le interazioni sono strettamente regolati per mantenere l&#39;omeostasi cellulare, come un cambiamento di questo equilibrio biologico gioca spesso un ruolo nella malattia e la trasformazione delle cellule tumorali. Proteine ​​di membrana associati sono tra la classe più importante di proteine ​​biologicament...

split-ubiquitin based membrane yeast two-hybrid (myth) system: a powerful tool for identifying protein-protein interactions

L&#39;importanza fondamentale biologici e clinici di proteine ​​di membrana integrali portato allo sviluppo di un lievito-based per la high-throughput identificazione di interazioni proteina-proteina (PPI) per la full-length proteine ​​transmembrana. A tal fine, il nostro laboratorio ha sviluppato il split-ubiquitina lievito base a membrana a due ibridi (MITO) del sistema. Questa tecnologia consente per la rilevazione delle interazioni proteina sensibile transitoria e stabile con<em&gt; Saccharomyces cerevisiae</em&gt; Come un organismo ospite. MITO sfrutta l&#39;osservazione che ubiquitina può essere separata in due frazioni stabili: il C-terminale di lievito ubiquitina (C<sub&gt; Ub</sub&gt;) E la N-terminale della frazione ubiquitina (N<sub&gt; Ub</sub&gt;). Nel mito, questo principio è adattati per essere utilizzati come un &#39;sensore&#39; di interazioni proteina-proteina. In breve, l&#39;integrale delle proteine ​​di membrana esca è fuso C<sub&gt; Ub</sub&gt; Che è legata ad un fattore di trascrizione artificiale. Proteine ​​prede, sia in formato singolo o una raccolta, si fondono alla N<sub&gt; Ub</sub&gt; Porzione. Interazione tra proteine ​​l&#39;esca e preda porta alla ricostituzione della combinazione di sostanze ubiquitina, formando un full-length &#39;pseudo-ubiquitina&#39; molecola. Questa molecola è a sua volta riconosciuto da enzimi citosolici deubiquitinating, con conseguente scissione del fattore di trascrizione, ed alla susseguente induzione dell&#39;espressione del gene giornalista. Il sistema è altamente adattabile, ed è particolarmente adatto a high-throughput screening. E &#39;stato impiegato con successo per studiare le interazioni con proteine ​​integrali di membrana da entrambi i lieviti ed altri organismi.
