이관능성 폴리뉴클레오티드 포스파타아제/키나아제사람에게서 PNKP [5][6][7]유전자에 의해 암호화되는 효소이다.결정화된 마우스 단백질의 상세한 구조 연구는 5'-폴리뉴클레오티드 키나제와 3'-폴리뉴클레오티드 포스파타아제 [8]활성을 모두 조사했다.펩타이드 배열의 추가 특징으로는 포크헤드 어소시에이션(FHA) 도메인, ATP 결합 부위 및 핵 및 미토콘드리아 국재 배열을 포함한다.

상호 작용

PNKP는 DNA 중합효소[9] 베타 및 XRCC1[9][10]상호작용하는 으로 나타났다.

신경 질환에서의 역할

PNKP를 코드하는 인간 유전자는 소두증, 발작 및 DNA 수복결함이 있는 환자에서[11][12][13][14] 돌연변이가 관찰되었다.열성 운동 실조증의 일종도 PNKP [15]돌연변이와 관련되어 있다.PNKP의 [16]새롭게 특징지어진 병리학적 변종도 있다.생쥐와 드로소필라와 같은 모델 유기체가 더 많은 통찰력을 [17][18]만들어내기 위해 사용되어 왔다.
