소포관련막단백질2(VAMP2)는 VAMP2유전자에 [5][6]의해 인간에게 암호화되는 단백질이다.
기능.
시냅토브레빈/VAMPs, 신트신 및 25-kD 시냅토솜 관련 단백질 SNAP25는 시냅스 전막과의 도킹 및/또는 융합에 관여하는 단백질 복합체의 주요 성분이다.VAMP2는 소포관련막단백질(VAMP)/시냅토브레빈 계열의 구성원이다.VAMP2는 도킹과 융합 사이의 단계에서 신경전달물질 방출에 관여하는 것으로 생각된다.기능성 시냅토브레빈2/VAMP2 유전자가 없는 생쥐는 출생 후 생존할 수 없으며 시냅스 전달이 극적으로 감소하여 [7]약 10%의 통제력을 가진다.단백질은 신트랜신, 시냅토좀 관련 단백질, 25kD 및 콤플렉신과 함께 안정적인 복합체를 형성한다.또한 시냅토피신과 [6]뚜렷한 콤플렉스를 형성합니다.
임상적 의의
VAMP2의 헤테로 접합 돌연변이는 저혈압과 자폐적 특징을 가진 신경 발달 장애를 일으킨다.[8][9][10]
