세린/트레오닌-단백질 키나제 PRP4 호몰로그 는 인간에서 PRPF4B 유전자 에 의해 암호화된 효소 다.[5] [6] [7]
프리 mRNA 스플리싱은 두 개의 순차적인 트랜지스터 단계에서 발생하며, 이 유전자에 의해 인코딩된 단백질은 프리 mRNA 스플리싱과 신호 전달에 관여하는 것으로 생각된다. 이 단백질은 세린/arginine이 풍부한 단백질 특유 키나제 및 사이클린 의존 키나제(CDKs)를 포함하는 키나제 계열에 속한다. 이 단백질은 미토겐 활성 단백질 키나제(MAPK)에 대한 동질감이 있는 CDK 유사키나아제(Clk)로 간주된다.[7]
상호작용 PRPF4B는 Pinin 과 상호작용 하는 것으로 나타났다.[8]
