HMGB2
HMGB2
고이동성 그룹 단백질 B2는 고이동성 그룹 단백질 2(HMG-2)로도 알려져 있으며 인체에서 HMGB2 [5][6]유전자에 의해 암호화되는 단백질이다.
기능.
이 유전자는 비히스톤 염색체 고이동성 그룹 단백질 [7]패밀리의 일원을 암호화한다.이 과의 단백질은 염색질 관련 단백질로 고급 진핵세포의 핵에 널리 분포되어 있다.체외 연구는 이 단백질이 DNA를 효율적으로 구부리고 DNA 서클을 형성할 수 있다는 것을 보여주었다.이러한 연구들은 DNA의 유연성을 촉진함으로써 시스 작용 단백질 사이의 협력적인 상호작용을 촉진하는 역할을 시사한다.이 단백질은 또한 DNA 이중 가닥 절단 복구 및 V(D)J [6]재조합의 DNA 말단 결합 과정의 최종 결찰 단계에 관여하는 것으로 보고되었다.

PMID 27799366. 노화 중 HMGB2(High-mobility group protein box 2)의 상실은 억제성 헤테로크로마틴을 SASP 유전자 위치에 확산시킴으로써 SASP 유전자 발현을 흐리게 한다.이는 SAHF(노년기 관련 헤테로크로마틴 포시)에 SASP 유전자 자리의 통합과 관련이 있으며, 이는 다시 SASP 유전자 발현을 억제한다.
