POU4F1
POU4F1뇌특이적 호메오박스/POU 도메인 단백질 3A(BRN3A), 호메오박스/POU 도메인 단백질 RDC-1 또는 Oct-T1로 알려진 POU 도메인, 클래스 4, 전사 인자 1(POU4F1)은 사람 내에서 POU4F1 [4][5]유전자에 의해 암호화되는 단백질이다.
BRN3A(POU4F1)는 발달하는 말초 감각 신경계(도랑근 신경절, 삼차 신경절, 후뇌 감각 신경절), 중추 신경계의 특정 영역, 신경사 세포라고 불리는 망막 뉴런 및 B- 및 T-림프세포의 세포에서 고도로 발현되는 등급 IV POU 도메인을 포함하는 전사 인자이다.를 [5][6]참조해 주세요.
검출
Brn3a는 원형 POU 전사 인자 Pit1(뇌하수체 특이 양성 전사 인자 1, Pou1f1), Oct1(Pou2f1) 및 Caenorhabditis elegans factor Unc86에 대한 상동성을 기반으로 생쥐에서 처음 발견되었으며 Brn3으로 [7]명명되었다.Brn3 유전자 클래스의 여러 구성원이 발견되었을 때,[6][8] 그것은 다른 그룹의 연구원들에 의해 Brn3.0과 Brn3a로 이름이 바뀌었다.그 후, 이 유전자는 마우스에서는 체계적으로 Pou4f1로, 인간에서는 POU4F1로 이름이 바뀌었다.단백질 제품은 여전히 Brn3a로 자주 언급된다.
기능.
감각 뉴런 외에도, 설치류와 조류(그리고 아마도 인간)에서 Brn3a는 척수, 중뇌 상부 콜로큘러스, 적색 핵, 모호한 핵, 하감람핵, 하베눌라, [9]망막을 포함한 중추 신경계의 여러 부위에서 발현됩니다.
Brn3a에서 null 돌연변이("노크아웃")를 가진 쥐는 [10][11][12]호흡에 필수적인 핵 모호성의 발달 결함으로 인해 출생 시 죽는다.
Brn3a는 하류 "표적" 유전자를 조절함으로써 발달에 작용하는 전사 인자이다.마이크로어레이는 말초 감각 [13][14]뉴런의 Brn3a 하류에 있는 많은 유전자를 결정하기 위해 사용되어 왔다.
감각뉴런에서 Brn3a는 LIM 도메인 전사인자 ISL1 또는 Islet1과 함께 [15]발현되며 Isl1과 공통되는 하류타깃이 많다.Pou4f1/Isl1 이중 돌연변이 쥐는 이중 돌연변이 쥐 [16]배아의 감각 뉴런에서 많은 하류 유전자의 조절에 강한 서한 효과를 보인다.
호모 접합성 Brn3a 눌 돌연변이는 생쥐에서 출생 시 치명적이지만 Brn3a 눌 헤테로 접합체는 알려진 표현형이 없다. 즉, Brn3a 눌 돌연변이는 완전히 열성이다.이는 헤테로 접합체 내에서 Pou4f1 유전자의 잔여 복사본의 발현이 증가하여 하류 [13]표적의 거의 정상적 발현으로 이어지는 자가 [17]조절에 의한 유전자 용량 보상으로 설명될 수 있다.헤테로 접합체에서의 호모 접합체 치사율과 용량 보상의 조합은 왜 POU4F1 돌연변이가 인간 질병에서 확인되지 않은지를 설명할 수 있으며, 질병은 POU 도메인 전사 인자 클래스의 여러 다른 구성원과 관련이 있다.
상호 작용
POU4F1은 에스트로겐 수용체 알파,[18] RIT2[19] 및 유잉 육종 중단점 영역 [20]1과 상호작용하는 것으로 나타났다.
