진핵생물번역개시인자 5A-1은 EIF5A 유전자에 [5]의해 인체 내에서 암호화되는 단백질이다.
폴리아민 스펠미딘의 특정 리신 잔기로 eIF5A에서 두 가지 촉매 [6]단계로 합성되는 특이 아미노산 하이푸신 [N-ε(4-아미노-2-히드록시부틸)-리신]을 함유하는 유일한 단백질이다.
EF-P는 eIF5A의 박테리아 상동성으로, 번역 후 유사하지만 뚜렷한 방식으로 [7][8]변형됩니다.두 단백질 모두 펩타이드 결합 형성을 촉매하고 리보솜 막힘을 해결하는 데 도움을 주는 것으로 믿어지며, 원래 [9]"개시 인자"라는 명칭에도 불구하고 신장 인자가 된다.
임상 관련성
생식계 유해 헤테로 접합 EIF5A 변종은 Faundes-Banka[10][11]증후군을 일으킨다.이 희귀한 인간 질환은 발달 지연, 소두증, 소두증, 소두증 및 비정형 특징의 다양한 조합으로 특징지어진다.
