# Introduction
Definition : Auto (Self) Phagy (Eating)
- 세포는 기아상태(starvation)가 되면 autophagy를 통하여 에너지원을 만듦으로써 세포가 생존할 수
있도록 한다.
Targets of autophagic degradation : 오래된 단백질, 단백질 집합체(Protein aggregates)
손상된 세포내 소기관, 세포 내 침투한 병원균,바이러스
Categorization of autophagy
# Macroautophagy, how it works ?
# How autophagy formed?
- 현재까지 30여 개의 autophagy-related (ATG) gene의 발견되었으며 이들은 진핵생물에서 모두 보존 되어있다.

# Macroautophagy, how it works ?
# How autophagy formed?
- 현재까지 30여 개의 autophagy-related (ATG) gene의 발견되었으며 이들은 진핵생물에서 모두 보존 되어있다.
- ATG 유전자들이 autophagosome이 만들어 지는 곳 (isolation membrane)으로 모인 후, elongation이 일어난다.
- ATG 유전자들에 의해 autophagosome이 만들어지면 LC3를 제외한 나머지 ATG 유전자들은 autophagosome에서 detech 된다. 따라서 LC3는 autophagosome의 marker로 사용된다.
- Two ubiquitin like conjugation systems
