호모 사피엔스에서 발견되는 포유류의 단백질
단백질 수송 단백질 Sec61 서브유닛 베타는 SEC61B [5] [6] [7] 유전자에 의해 인체에서 암호화되는 단백질 이다.
Sec61 복합체는 소포체 (ER) 막의 단백질 전위 장치의 중심 성분이다. Sec61 복합체는 단백질이 ER 막에 걸쳐 위치하여 통합되는 막 통과 채널을 형성한다. 이 복합체는 알파, 베타, 감마라는 세 가지 막 단백질로 구성되어 있다. 이 유전자는 베타 서브유닛 단백질을 암호화한다. Sec61 서브유닛은 ER 후 구획에서도 관찰되며, 이는 이러한 단백질이 ER을 빠져나와 재활용될 수 있음을 시사한다. 이 [7] 전사물에 대한 다중 폴리아데닐화 부위의 증거가 있다.
