미생물학 생화학 세포생물학 유전체학

단백질(protein)은 생체를 이루는 주요 구성성분일 뿐만 아니라 다양한 구조를 형성하여 여러 가지 생리 기능을 수행함으로써 생명 현상의 발현과 조절에 핵심적인 역할을 담당한다. 본 연구실은 여러 가지 기능유전체학(functional genomics) 및 단백체학(proteomics)적 방법을 사용하여 현대 생물학의 주요 연구모델인 효모(Saccharomyces cerevisiae)와 인간 세포주에서 세포 기능 조절과 관련된 단백질들을 새로이 발굴하고 분자 수준에서 그들의 작용 기전을 규명하는 것을 연구 목표로 삼고 있다. 또한 2013년 11월에 창업한 바이오벤처기업 (주)지피씨알(http://gpcr.co.kr)을 통해 환자맞춤형 항암치료제(personalized cancer therapeutics)를 개발함으로써 기초연구성과의 산업적 가치 발굴과 활용을 적극 추구하고자 한다.
   
1. Functional study of human GPCR heterodimers

GPCR (G-protein-coupled receptor)은 세포 외부로부터의 자극을 세포 내 신호전달경로로 매개해주는 세포 표면 수용체로서 인체의 주요 약물표적으로 작용한다. 최근에는 GPCR heterodimerization이 GPCR의 실질적인 기능 발현 및 조절에 매우 중요한 역할을 한다는 사실이 새로이 밝혀지고 있다. 본 연구에서는 GPCR heterodimerization 네트워크를 체계적으로 분석하고, heterodimerization에 의한 GPCR의 기능 조절 기전을 규명하며, 이를 바탕으로 GPCR heterodimer 기능 제어를 통한 질병 치료 방안을 탐구하고자 한다.

  (2) Investigation of functional roles of GPCR heterodimerization
  (3) Development of drugs targeting GPCR heterodimers

2. Dissection of signaling pathways regulating cell growth, proliferation, and death

세포의 분열, 성장, 증식, 노화, 사멸은 가장 본질적인 생명 현상이다. 본 연구에서는 이 과정에 관여하는 TOR (target of rapamycin) signaling pathway, autophagy, rDNA (ribosomal DNA) silencing 등과 관련된 신규 조절 인자를 발굴하고 그 기능을 분석, 연구한다.

  (2) Relationship between TOR signaling pathway and autophagy
  (3) Investigation of rDNA silencing factors

3. In vivo analysis of protein interaction network using BiFC assay

정교한 생명 현상의 발현 및 조절은 궁극적으로 세포 내 다양한 단백질들 간의 상호작용 네트워크를 통해 일어나게 된다. 따라서 생명 현상의 본질을 이해하기 위해선 단백질 상호작용 분석이 필수적이다. 본 연구에서는 살아있는 세포에서 단백질 상호작용을 직접 관측할 수 있는 BiFC (bimolecular fluorescence complementation) assay를 이용하여 유전체 수준(genome-wide level)에서 단백질 상호작용을 분석, 연구한다.
