<p><strong>Vědci z Ústavu organické chemie a biochemie AV ČR pronikají do detailů genové transkripce. Popsali dosud neznámý molekulární mechanismus, kterým může začínat přepis genetické informace z deoxyribonukleové kyseliny (DNA) do ribonukleové kyseliny (RNA). Zaměřili se na zvláštní molekuly nazývané alarmony, které se vyskytují v buňkách napříč organismy a jejichž hladina se často zvyšuje při buněčném stresu.

U eukaryotních organismů, kam patří i lidské buňky, je nejznámější čepička, která se podílí na stabilitě RNA a regulaci jejího dalšího osudu. V posledních letech se však ukazuje, že existují i alternativní, nekanonické RNA čepičky, jejichž vznik a mechanismus připojení k RNA se zatím vymyká lidským znalostem. Mezi ně patří například tzv. alarmonové čepičky, tvořené molekulami dinukleosidpolyfosfátu, alarmonů, které chrání buněčnou RNA ve chvílích, kdy je buňka v ohrožení.</p><p>Tým <a target="_blank" rel="noopener noreferrer" href="https://cahova.group.uochb.cz/cs"><strong>Dr. Hany Cahové</strong></a> se ve své studii zaměřil na RNA polymerázu z bakterií a sledoval, jakým způsobem může tento enzym zahájit transkripci za využití dinukleosidpolyfosfátů (NpNs) místo běžných stavebních bloků RNA. Vědci vůbec poprvé popsali na atomární úrovni, jak může vznikat RNA s alarmonovou čepičkou přímo při zahájení přepisu genu. Navíc pozorovali, že se Np<sub>n</sub>Ns vážou jiným typem párování, než je obvyklé.</p><p>Na práci se zásadně podílely <strong>Valentina Serianni z týmu Hany Cahové</strong>, která prokázala schopnost dinukleosidpolyfosfátů zahajovat přepis genu, a<strong> Jana Škerlová</strong>, která se zaměřila na strukturální analýzu RNA polymerázy a na základě dat z kryogenní elektronové mikroskopie ukázala, jak se molekuly dinukleosidpolyfosfátů váží do aktivního místa RNA polymerázy, tedy do srdce enzymu, kde se genetická informace přepisuje. Jejich studie pomáhá odhalovat procesy, které provázejí přepis genetické informace z DNA do RNA.</p><p>Hana Cahová k tomu dodává: <i>„Popisujeme něco, co se v buňkách skutečně děje a co nyní dokážeme pozorovat přímo na úrovni jednotlivých molekul. Získáváme tak odpovědi na zásadní otázky týkající se buněčných procesů, například jak se buňky přizpůsobují stresu. Právě RNA totiž přenáší kaskádu informací, které stojí za jakoukoli buněčnou reakcí, např. na stav ohrožení způsobený nedostatkem živin či teplotním šokem.“</i></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg" alt="ÚOCHB/Tomáš Belloň: Výzkum z ÚOCHB odhaluje dosud nepoznaný způsob přepisu genetické informace: Dr. Tomáš Kouba, vedoucí core facillity skupiny Kryogenní elektronová mikroskopie." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg 234w," sizes="100vw" width="2000" height="1335"></p><div><p>Klíčovou roli v projektu sehrála kryogenní elektronová mikroskopie (cryo-EM), kterou ved<strong>l Dr. Tomáš Kouba</strong>, jeden z autorů článku. <i>„Kryoelektronová mikroskopie umožňuje zmrazit biologické molekuly skoro v jejich přirozené formě a následné získat trojrozměrnou strukturu takových molekul.

Pravděpodobný mechanismus tohoto specifického typu zakončení RNA spočívá v přímém začlenění dinukleosidových polyfosfátů RNA polymerázou jako nekanonických iniciačních nukleotidů. Dosud však nebylo známo, jakým způsobem se tyto sloučeniny vážou do aktivního místa RNA polymerázy během zahájení transkripce. V této práci jsme in vitro studovali iniciaci transkripce za použití série DNA templátů v kombinaci s dinukleosidovými polyfosfáty a modelovou RNA polymerázou z bakterie <i>Thermus thermophilus</i>. Zjistili jsme, že místo zahájení transkripce se může lišit v závislosti na kompatibilitě konkrétního templátu a použitého dinukleosidového polyfosfátu. Struktury iniciačních transkripčních komplexů s dinukleosidovými polyfosfáty získané pomocí kryogenní elektronové mikroskopie odhalily, že obě nukleové báze v molekule mohou párovat s DNA templátem. První kódovaný nukleotid se páruje kanonickým Watsonovým–Crickovým způsobem, zatímco druhá nukleová báze se váže nekanonicky prostřednictvím reverzního Watsonova–Crickova párování. Tato práce tak poskytuje strukturní vysvětlení mechanismu, kterým dinukleosidové polyfosfáty zahajují transkripci RNA.</p></div></div>
