İlk Maya Prionlar onların sıradışı fenotipleri ve şaşırtıcı desenleri miras tarafından tespit edilmiştir. Bu Prionlar özellikleri sonra algoritmaları ve ekrana ek prion protein için Hesaplama araçları oluşturmak için kullanılan. Burada, açıklanan yöntemi buna ek olarak, deneysel ve geçici overexpression protein uyum içinde devlet olarak kodlanmış kalıcı bir değişiklik-a kararlı oluşturmak için kullanır.

Biyolojik sistemlerin sık protein bereket geçici dalgalanmalar deneyim. Bunlar bir organizmanın veya gelecek nesillerin fenotip şekillenmesinde kalıcı bir etkisi olup belirsizdir. Bu Biyoloji en iyi bilinen örnekleri proteinlerin, genom yapılmaksızın kalıtsal özellikleri ortaya çıkması sürücü Prionlar nadir bir sınıf içerir. Bunun yerine, bu proteinaceous ve içindefectious parçacıklar fenotipleri protein conformation1,2için kendi kendini devam ettiren değişiklikleri yoluyla iletmek. Bu tür devralma alışılmadık kalıtım kalıpları bir yıkıcı nörodejeneratif hastalığın nedeni olarak keşfedilmiştir. Ancak, mantar memeliler3,4,5,6,7,8,9,10 ' a kadar çeşitli organizmalar çalışmalarda beri deli dana gibi öğeleri adaptif değer görüşmek indirdik. Yine de, Prionlar büyüleyici bir nadir biyolojik gariplik olarak incelendi var.
Protein bazlı devralma karakterizasyonu uzun örnekler küçük bir kümesi tarafından kısıtlanmış çünkü bu egemen bilgelik kısmen düzenlenmektedir. Son sistematik tarama çabaları bu resim önemli ölçüde yakıt deli dana gibi konformasyon dönüşüm kapasitesine sahip birkaç yeni bona fide Prionlar11 ve yaklaşık iki düzine protein etki alanları12 tespit ederek genişletilmiş. Ancak, bu yaklaşımlar genellikle güçlü amino asit dizisi önyargıları üzerinde odaklanmıştır çünkü keşfedildi Prionlar kurucu Maya Prionlar [PSI+]13,14, [URE3]15ve [RNQ+]11,16biyokimyasal özelliklerini paylaşır. Bu içerir: asparagine (N) ve glutamin (Q), 2) bir amiloid [PRION+] conformation17,18,19, derlemeye uzun polimer menziller bakımından zengin olan ve 3) tam güven disaggregase kız13,20,21anneden sadık yayma için Hsp104 işlev 1) Modüler etki alanları. Dahil olmak üzere, birçok bona fide Prionlar, [GAR+], [Het-s] ve hatta orijinal prion (PrPSc), böyle sıkı kriterleri altında özledim. Belki daha da önemlisi, herhangi bir roman mekanizmaları protein bazlı devralma22yakalamak mümkün olacaktır. Böylece, bu tür olayların gerçek biyolojik etki derecesini daha önceden kabul doğada çok daha yaygın olabilir.
Bu soruyu araştırmak için bir yüksek üretilen iş, Proteom çapındaki strateji istihdam edildi. PrPSc, [GAR+], dahil olmak üzere tüm Prionlar damgasını ve [Het-s], nedensel proteinlerin geçici overexpression kuvvetle deli dana Alım15,23,24,25,26oranını arttırır. İstikrarlı protein bazlı, epigenetik Birleşik geçici bireysel proteinlerin overexpression inducing tarafından başlatılan Eğer biz sistematik olarak sormak, karşıdan karşıya tüm ORFeome, Maya için bu özelliği kullandı. Bu protein overexpression fenotipleri27değiştirebilirsiniz de bilinir. Ancak, birçok nesiller ilk overexpression sonra yüzlerce kalıtsal fenotip bir değişiklik geçici onların aşırı üretimi üretir çünkü prion proteinleri alışılmadık. Daha önce bu özelliğin avantajlarından, hem de genetik öğeleri protein bazlı heritably fenotipik manzara genom28değiştirmeden yeniden kablolama özelliği olan proteinler onlarca tanımlamak için sıradışı kalıtım kalıpları aldı. Bazı rağmen tespit proteinler daha önce bilinen Prionlar, en yeni formlar protein bazlı miras ortaya çıkarmak için bu yaklaşım gücünü vurgulayan değildi.

high-throughput screening for protein-based inheritance in s. cerevisiae

Gelecek nesillere biyolojik bilgilerin kodlama genellikle DNA dizisi değişiklikler yoluyla elde edilir. Uzun ömürlü devralma protein biçimi (yerine sıra) kodlanmış uzun paradigma kayması ama nadir olarak incelendi. En iyi karakterize epigenetik gibi öğeleri yeni fenotipleri kalıtsal tezahürü sürücü kendi kendine montaj bir davranış sahip Prionlar örnekleridir. Birçok arketipik Prionlar çarpıcı bir N/Q-zengin sıra önyargı görüntülemek ve amiloid bir sürüye bir araya. Bu sıradışı özellikler yeni prion protein tanımlamada çoğu tarama çabaları bildirdi. Ancak, en az üç bilinen Prionlar (kurucu prion, PrPScde dahil olmak üzere) bu biyokimyasal özellikleri liman değil. Biz bu nedenle kitlesel eylem bir özelliğine göre protein bazlı devralma kapsamını soruşturma için alternatif bir yöntem geliştirdik: hangi bir öz-şablon uyum elde frekans prion protein geçici overexpression artırır. Bu yazıda Maya ORFeome kapasitesi protein bazlı devralma temin için analiz etmek için bir yöntem açıklanır. Bu stratejiyi kullanarak, daha önce bulduk &gt; Maya proteinlerin % 1 uzun ömürlü, sağlam, ve genetik mutasyon daha sık ortaya çıkan biyolojik özellikleri ortaya çıkması yakıt. Bu yaklaşım içinde yüksek üretilen iş karşıdan karşıya tüm ORFeomes veya belirli genetik ağlar veya çevresel uyaranlara için hedeflenen tarama paradigma olarak istihdam edilebilir. Sadece ileri genetik ekranlar çok sayıda gelişimsel ve sinyal yolları tanımladıkça, bu teknikleri protein bazlı miras biyolojik süreçlerin etkisini araştırmak için bir yöntem sağlar.

Protein overexpression is known to dramatically alter cellular phenotypes27. Indeed, with an initial screening approach, hundreds of new phenotypes were reproducibly recovered from the overexpression of clones from the yeast ORFeome using just ten stressors. However, the assays described above allow for the assessment of whether cells retain any long-term stable phenotypes following this overexpression. One protein capable of encoding such a state is Psp1. Psp1 is ...
