目标/特异性 | ULK1 (D8H5) Rabbit mAb, Atg13 (D4P1K) Rabbit mAb, FIP200 (D10D11) Rabbit mAb, and Atg101 (E1Z4W) Rabbit mAb recognize total endogenous levels of the corresponding target proteins irrespective of phosphorylation state. Phospho-ULK1 (Ser555) (D1H4) Rabbit mAb detects endogenous levels of ULK1 only when phosphorylated at Ser555 of mouse ULK1 (equivalent to Ser556 of human ULK1). Bands of unknown origin are detected between 90 and 100 kDa. Phospho-ULK1 (Ser757) (D7O6U) Rabbit mAb recognizes endogenous levels of ULK1 protein only when phosphorylated at Ser757 of mouse ULK1 (equivalent to Ser758 of human ULK1). |

背景 | Autophagy is a catabolic process for the autophagosomic-lysosomal degradation of bulk cytoplasmic contents (1,2). Autophagy is generally activated by conditions of nutrient deprivation but has also been associated with a number of physiological processes including development, differentiation, neurodegeneration, infection, and cancer (3). The molecular machinery of autophagy was largely discovered in yeast and referred to as autophagy-related (Atg) genes. ULK1, Atg13, and FIP200 form a complex that localizes to autophagic isolation membranes and regulates autophagosome biogenesis (4-6). mTOR phosphorylates both Atg13 and ULK1, suppressing ULK1 kinase activity and autophagy (5-7). Interaction between Atg101 and Atg13 can be important for the stability and basal phosphorylation of Atg13 and ULK1 (8,9). AMPK, activated during low nutrient conditions, directly phosphorylates ULK1 at multiple sites including Ser317, Ser555, and Ser777 (7,10). Conversely, mTOR, which is a regulator of cell growth and is an inhibitor of autophagy, phosphorylates ULK1 at Ser757 and disrupts the interaction between ULK1 and AMPK (7). |

After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO® is added and emits light during enzyme catalyzed decomposition. | |
Western blot analysis of extracts from MCF7 cells, untreated or treated with oligomycin #9996 (0.5 μM, 30 minutes), and C2C12 cells, untreated or treated with hydrogen peroxide (10 mM, 5 minutes), using Phospho-ULK1 (Ser555) (D1H4) Rabbit mAb. | |
Western blot analysis of extracts from MCF7 cells, untreated or treated with oligomycin #9996 (0.5 µM, 30 minutes), using Phospho-ULK1 (Ser555) (D1H4) Rabbit mAb (left). Phospho-specificity is demonstrated by pre-incubating the antibody with phosphorylated (middle) or non-phosphorylated peptides (right) against a region surrounding Ser555 of ULK1. | |
