호모 사피엔스 종의 단백질 코드 유전자
AP-1 복합 서브유닛 시그마-1A 는 사람에게서 AP1S1 [5] [6] [7] 유전자에 의해 암호화되는 단백질 이다.
기능. 이 유전자에 의해 암호화된 단백질은 클래트린을 코팅된 소포의 수용체와 연결 하는 클래트린 외피 집합체 복합체의 일부입니다. 이 소포들은 세포내막증 및 골지처리에 관여한다. 이 단백질은 베타 프라임 아답틴, 감마 아답틴 및 중간 사슬 AP47과 함께 골지 소포에 위치한 AP-1 조립 단백질 복합체를 형성한다. 이 유전자의 두 가지 대체 스플라이스된 전사 변이가 [7] 보고되었으며, 이는 별개의 등형식을 코드한다.
AP1S1의 돌연변이는 2008년에 [8] 기술된 희귀 가족성 MEDNIK 증후군을 일으킨다.
상호 작용 AP1S1은 AP1G1 [6] [9] [10] 및 RAB10과 [11] 상호 작용하는 것 으로 나타났습니다.
