| 产品介绍 | A major contributor to cellular homeostasis is the ability of the cell to strike a balance between the formation and degradation/removal of its cellular components. This process of internal cellular turn-over is called autophagy (self-eating), and is facilitated by a pathway of around 16 interacting proteins in the human. LC3, a ubiquitin-like modifier protein, is the human homolog of yeast Apg8 and is involved in the formation of autophagosomal vacuoles, called autophagosomes. LC3 is expressed as 3 splice variants (LC3A, LC3B and LC3C), which exhibit different tissue distributions and are processed into cytosolic and autophagosomal membrane-bound forms, termed LC3-I and LC3-II, respectively. A disruption to the autophagic process is now associated with the progression of several cancers, neurodegenerative disorders and cardiac pathologies, where LC3 is widely employed as a marker for autophagy. Function: Probably involved in formation of autophagosomal vacuoles (autophagosomes). Subunit: 3 different light chains, LC1, LC2 and LC3, can associate with MAP1A and MAP1B proteins. Interacts with SQSTM1. Interacts with TP53INP1 and TP53INP2. Subcellular Location: Cytoplasmic. Endomembrane system; Lipid-anchor. Cytoplasmic vesicle, autophagosome membrane; Lipid-anchor. Note: LC3B binds to the autophagic membranes. Tissue Specificity: Most abundant in heart, brain, liver, skeletal muscle and testis but absent in thymus and peripheral blood leukocytes. Post-translational modifications: The precursor molecule is cleaved by APG4B/ATG4B to form the cytosolic form, LC3-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, LC3-II. Similarity: Belongs to the MAP1 LC3 family.

文献和实验。 自噬发生与调节： 自噬的诱导主要由 ULK1、FIP200、Atg13 三种蛋白形成的ULK1复合物与雷帕霉素靶蛋白复合物1(mTORC1)之间相互作用实现的，成核过程与ClassIII PI3K(Vps34)-Beclin-1 复合物密切相关。自噬体在延伸阶段主要依赖于两个泛素化复合系统，即 Atg12 的结合过程与 LC3 的修饰过程，且都需要泛素活化酶 E1 和 E2 的参与。自噬体的成熟主要是指自噬体通过微管骨架，在转运必须内吞体分类复合物(ESCRT)和单体 GTP 酶
点相当于一个自噬体，可以通过计数来评价自噬活性的高低。 3. 利用 Western Blot 检测 LC3-II/I 比值的变化以评价自噬形成 自噬形成时，胞浆型 LC3（即 LC3-I）会酶解掉一小段多肽，转变为（自噬体）膜型（即 LC3-II），因此，LC3-II/I 比值的大小可估计自噬水平的高低。 LC3 抗体对 LC3-II 有更高的亲和力，会造成假阳性。方法 2 和 3 需结合使用，同时需考虑溶酶体活性的影响。 4. MDC 染色 MDC 染色
