임포틴 알파-3 으로도 알려진 카리오페린 서브유닛 알파-4 는 인간 에서 KPNA4 [5] [6] 단백질 이다.
기능. 핵친화성 단백질의 핵 수입은 핵 국재 신호(NLS)라고 불리는 짧은 아미노산 배열에 의해 지시된다. 카리오페린 또는 임포틴은 NLS를 인식하고 NLS를 포함한 단백질을 핵공 복합체에 도킹하는 세포질 단백질이다. 이 유전자에 의해 암호화된 단백질은 Xenopus importin-alpha 및 Saccharomyces cerevisiae Srp1과 배열 유사성을 공유한다. 이 단백질은 DNA 헬리케이스 Q1 및 SV40 T [7]
상호 작용 KPNA4는 RECQL [5] 및 STAT3와 [8] 것 으로 나타났다.
