Wgląd w specyficzność wiązania peptydów na końcu C domeny PDZ neuronalnej syntazy tlenku azotu

Neuronowa syntaza tlenku azotu, w przeciwieństwie do jej śródbłonkowych i indukowalnych odpowiedników, wykazuje domenę PDZ (PSD-95/Dlg/ZO-1) zlokalizowaną na jej końcu N zaangażowaną w celowanie subkomórkowe. C-końce różnych białek komórkowych wstawiają się w bruzdę wiążącą tej domeny PDZ i określają subkomórkową dystrybucję neuronalnego NOS (nNOS). Mechanizmy molekularne leżące u podstaw tych interakcji są słabo poznane, ponieważ domena PDZ nNOS może najwyraźniej wykazywać specyficzność wiązania klasy I, klasy II i klasy III.

Ponadto ostatnio zasugerowano, że domena PDZ nNOS wiąże się z bardzo niskim powinowactwem z C-końcami białek docelowych i aby doszło do wiązania, musi zajść konieczna równoczesna interakcja boczna. Opisujemy tutaj, że domena PDZ nNOS może zachowywać się jak domena PDZ klasy III w dobrej wierze i wiązać się z sekwencjami C-końcowymi z resztami kwasowymi w pozycji P-2 z niskimi mikromolowymi stałymi wiązaniami. Wiązanie z sekwencjami C-końcowymi z resztą hydrofobową w pozycji P-2 oraz resztą kwasową w pozycji P-3 (klasa II) może również wystąpić, chociaż interakcje obejmujące reszty rozciągające się do pozycji P-7 pośredniczą w tego typu wiążący.

To rozwiązłe zachowanie rozciąga się również na jego powiązanie z sekwencjami klasy I, które muszą wykazywać resztę Glu w P-3 i resztę Thr w P-2 Za pomocą ukierunkowanej mutagenezy i spektroskopii NMR byliśmy w stanie zidentyfikować reszty zaangażowanych w każdy konkretny rodzaj wiązania i zracjonalizować mechanizmy stosowane do rozpoznawania partnerów wiążących.

Na koniec przeanalizowaliśmy związek o wysokim powinowactwie domeny PDZ nNOS z klaudyną-3 i klaudyną-14, dwoma ściśle połączonymi białkami błonowymi tetraspanowymi, które są niezbędnymi składnikami bariery parakomórkowej.

 

Wcześniejsze badania wykazały, że c-jun i neuronalna syntaza tlenku azotu (nNOS) są indukowane w uszkodzonych neuronach ruchowych, ale ich rola w śmierci neuronów ruchowych pozostaje niejasna.

  • Postawiliśmy hipotezę, że nNOS może być dalszym efektorem kinazy N-końcowej c-jun (JNK)/c-jun w śmierci neuronu ruchowego wywołanej oderwaniem. Tutaj odkryliśmy, że oderwanie korzenia ramiennego wywołało przejściowy wzrost aktywności JNK i odpowiednio trzy- i czterokrotny wzrost fosfo-c-jun i c-jun; jednak oderwanie korzenia ramiennego spowodowało zmniejszenie ekspresji białka nNOS od 4 godzin do 14 dni po urazie.
  • W 14 dni po urazie prawie wszystkie neurony ruchowe nNOS-dodatnie były zlokalizowane razem z neuronami ruchowymi fosfo-c-jun-dodatnimi w ipsilateralnych rogach brzusznych.
  • Inhibitor JNK SP600125, zastosowany bezpośrednio po urazie, powodował podwyższenie poziomu białka nNOS zarówno w uszkodzonych rdzeniach kręgowych, jak i neuronach ruchowych i powodował niewielkie złagodzenie śmierci neuronów ruchowych poprzez hamowanie fosforylacji c-jun 14 dni po urazie.
  • Nasze wyniki wykazały, że szlak transdukcji sygnału JNK/c-jun jest zaangażowany w oderwanie korzenia. Hamowanie fosforylacji c-jun zapobiega spadkowi poziomów nNOS poniżej poziomu wyjściowego w rdzeniu kręgowym i częściowo łagodzi śmierć neuronu ruchowego po wyrwaniu korzenia.
  • W związku z tym hamowanie fosforylacji c-jun lub zwiększanie poziomu białka nNOS w uszkodzonym rdzeniu kręgowym na wczesnym etapie może zostać wykorzystane w przyszłości jako strategie celów molekularnych w zapobieganiu degeneracji neuronów ruchowych podczas wybijania korzeni.

 

Ogon C-końcowy (CT) neuronalnej syntazy tlenku azotu (nNOS) jest elementem regulatorowym, który hamuje aktywność nNOS przy braku związanej kalmoduliny (CaM).

Struktura krystaliczna domeny reduktazy nNOS (nNOSr) (Garcin, ED, Bruns, CM, Lloyd, SJ, Hosfield, DJ, Tiso, M., Gachhui, R., Stuehr, DJ, Tainer, JA i Getzoff, ED (2004) J. Biol. Chem. 279, 37918-37927) ujawnili, w jaki sposób pierwsza połowa CT oddziałuje z nNOSr, a zatem dostarczyli szablonu do szczegółowych badań. Wygenerowaliśmy mutanty skrócone w nNOS i nNOSr, aby przetestować znaczenie 3 różnych regionów CT.

Wyeliminowanie końcowej połowy CT (wszystkich reszt od Ile1413 do Ser1429), która jest niewidoczna w strukturze kryształu, nie miało prawie żadnego wpływu na uwalnianie NADP+, redukcję flawiny, autooksydację flawiny, redukcję hemu, aktywność reduktazy lub aktywność syntezy NO, ale zapobiegał wzrostowi ekranowania FMN, który normalnie występuje w odpowiedzi na wiązanie NADPH.

Dodatkowe usunięcie alfa-helisy CT (reszty 1401 do 1412) znacząco zwiększyło szybkość uwalniania NADP+, autooksydację flawiny i aktywność oksydazy NADPH oraz spowodowało nadmierne odsłanianie kofaktora FMN. Efekty te były związane ze zwiększoną aktywnością reduktazy i nieznacznie zmniejszoną redukcją hemu i syntezą NO.

Dalsze usuwanie reszt za Gly1396 (pełne skrócenie CT) wzmocniło wyżej wymienione efekty, a ponadto zmieniło oddziaływanie NADP+ z FAD, złagodziło kinetyczną supresję redukcji flawiny i dalej zmniejszyło redukcję hemu i syntezę NO. Nasze wyniki pokazują, że CT wywiera zarówno wieloaspektowy, jak i regiospecyficzny wpływ na aktywność katalityczną i powiązane zachowania, a tym samym dostarcza nowego wglądu w mechanizmy regulujące katalizę nNOS.

Domeny PDZ to wielofunkcyjne motywy interakcji białek, które często wiążą się z C-końcem docelowych białek. Tlenek azotu (NO), endogenna cząsteczka sygnałowa, odgrywa kluczową rolę w funkcjonowaniu układu nerwowego, odpornościowego i sercowo-naczyniowego. Chociaż istnieje wiele funkcji fizjologicznych dla pochodzącego z neuronów NO, wytwarzanego głównie przez neuronalną syntazę NO (nNOS), nadmierna aktywność nNOS pośredniczy w uszkodzeniu mózgu w niedokrwieniu mózgu i w zwierzęcych modelach choroby Parkinsona.

Dlatego też subkomórkowa lokalizacja aktywności nNOS musi być ściśle regulowana. Aby określić ligandy domeny PDZ nNOS, przeszukaliśmy 13 miliardów różnych peptydów i odkryliśmy, że domena nNOS-PDZ wiąże się ściśle z peptydami kończącymi się Asp-X-Val. Różni się to od jedynego znanego konsensusu (Thr/Ser)-X-Val, który oddziałuje z domenami PDZ z PSD-95. W preferencji dla Asp w pozycji peptydu -2 pośredniczy Tyr-77 z nNOS. Podstawienie Y77D78 do H77E78 zmienia specyficzność wiązania z Asp-X-Val na Thr-X-Val. Kierując się konsensusem Asp-X-Val, zidentyfikowano kandydujące białka oddziałujące z nNOS, w tym receptory glutaminianu i melatoniny. Nasze wyniki pokazują, że domeny PDZ mają wyraźną specyficzność wiązania peptydów.
