  1. cikk-referáló Génátírás szabályozása: transzkripciós mechanizmusok Dr. Marcsek Zoltán

  2. Génexpresszió fenotípus DNA in cell Courtesy The Protein Society mRNA protein

  3. eukaryoták promóter elemei • a promóter elemei többé-kevésbé jól definiáltak • a transzkripció start helyétől különböző távolságra vannak gyakran hiányzik általában van

  4. egy tipikus promóter

  5. az eukaryota transzkripció szabályozása

  6. szabályozás transzkripciós faktorokkal • egy transzkripciós faktor (vagy transzkripciós faktorok egy csoportja) egy géncsoport expresszióját szabályozhatja (pl. heat shock fehérjék, G1/S restrikciós pont fehérjék, stb) • egy gén átírását egy vagy több, egymástól független transzkripciós faktor szabályozhatja (pl. metallothionine) • magas expresszió kiváltásához gyakran több, különböző 'response' elemhez kötő transzkripciós faktor lehet szükséges

  8. NFkB mi az, mit csinál, miért jó, ha ismerjük? transzkripciós faktor

  9. NFkB • Baltimore & Sen fedezték fel mint egy B-sejt-specifikus magi proteint amely az immunoglobulin kkönnyű láncának meghatározott szekvenciájához kötődik és a gén átírását serkenti (enhancer) (Cell 47:921-928, 1986) • az NFkB a Rel transzkripciós faktor családba tartozik amely nagyszámú, az immunválasszal, a gyulladással, a sejtosztódással és apoptózissal összefüggő gén expresszióját szabályozza • az emlős sejtekben öt eltérő NFkB (rel) alegységet ismerünk amelyek kb. 300 nagyon konzervált aminosat tartalmaznak • a citoplazmában az NFkB inaktív formában több, különböző kombinációban található (heterodimer p50/p65 (Rel A) és az inhibítor IkBaalegység)

  10. Family of NFkB and Inhibitory kB (IkB) proteins Nat.Rev.Cancer 2:301-310, 2002

  11. p105 (contains p50 NFkB1) • Name: p105 (contains p50 subunit, a.k.a. NFkB1) • Descr: Once in the nucleus initiates transcription of hundreds of genes • Length: 968

  12. p100 (contains p52 NFkB2) • Name: p100 (contains p52 subunit, a.k.a. NFkB2) • Descr: Once in the nucleus initiates transcription of hundreds of genes • Length: 899

  13. IkB • Name: Inhibitor of NF kappaB beta • Length: 356 • Consists mostly of ankyrin repeats that serve inhibitory function

  14. IkB • Name: IkappaB epsilon • Length: 361 • Consists mostly of ankyrin repeats that serve inhibitory function

  15. IKK Name: IKappaB kinase alpha Descr: Forms complexes with IKK Length: 745 aa Conserved Serine/Threonine protein kinase Domain detected at 10 – 300 aa.

  16. IKK • Name: IKappaB kinase beta • Descr: Forms complexes with IKK and destroys IkB’s • Length: 756 Similarly to IKK a slightly less conserved Serine/Threonine protein kinase Domain detected at 10 - 290 aa.

  17. IKK • Name: IKappaB kinase gamma • Length: 487 aa Contains Chromosome segregation ATPases domain

  18. az NFkB aktiválása • NFkB a citoplazmában található inaktív formában mint az IkBa inhibítorához kötött p50/65heterodimer • extracelluláris indukciós hatásra az IkBa-kinázkomplex (IKK) aktiválódik és foszforilálja az IkBa-t(szerin 32 és 36) amelyaz IkBalizin21 éslizin22 ubiquin-kötését okozza • ez az IkBaalegység lebotását eredményezi (26S proteasome) • az inhibitor alegység lebomlása a p50/p65 komplex aktivációját eredményezi: az NFkB a citoplazmából a sejtmagba kerül (transzlokáció) • a sejtmagban az NFkB transzkripciós faktor a ‘consensus szekvenciához’ (5’-GGGACTTTC-3’) kötődik és aktiválja a specifikus gének expresszióját
