Description

The rapid protocol (RP) PathScan® RP Total Atg14 Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Atg14 protein in a reduced assay time of 1.5 hours. Incubation of cell lysates and detection antibody on the coated microwell plate forms a sandwich with Atg14 in a single step. The plate is then extensively washed and TMB reagent is added for signal development. The magnitude of absorbance for the developed color is proportional to the quantity of Atg14.

*Antibodies in this kit are custom formulations specific to kit.

Specificity/Sensitivity

The PathScan® RP Total Atg14 Sandwich ELISA Kit detects endogenous levels of Atg14 protein. The kit sensitivity is shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

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 is also 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 is directed by a number of autophagy-related (Atg) genes. These proteins are involved in the formation of autophagosomes, cytoplasmic vacuoles that are delivered to lysosomes for degradation. The class III type phosphoinositide 3-kinase (PI3K) Vps34 regulates vacuolar trafficking and autophagy (4,5). Multiple proteins associate with Vps34, including p105/Vps15, Beclin-1, UVRAG, Atg14, and Rubicon, to determine Vps34 function (6-12). Atg14 and Rubicon were identified based on their ability to bind to Beclin-1 and participate in unique complexes with opposing functions (9-12). Rubicon, which localizes to the endosome and lysosome, inhibits Vps34 lipid kinase activity; knockdown of Rubicon enhances autophagy and endocytic trafficking (11,12). In contrast, Atg14 localizes to autophagosomes, isolation membranes and ER, and can enhance Vps34 activity. Knockdown of Atg14 inhibits starvation-induced autophagy (11,12).

    图 1. 与仅用 Atg14 表达载体进行转染的细胞相比,带有人 Atg14 和小鼠 ULK1 表达载体的 293T 细胞的共转染增加了Atg14 在 Ser29 位点的磷酸化,但不影响总 Atg14 的水平。与模拟转染细胞相比,Atg14 在用 Atg14 表达构建体转染的 293T 细胞中也高度表达。共转染 Atg14/ULK1、仅转染 Atg14 和转染空载 293T 细胞的裂解物蛋白浓度与使用 PathScan® RP Total Atg14 Sandwich ELISA Kit #26160 时在 450 nm 处的吸光度之间的关系如上图所示。使用 phospho-Atg14 (Ser29) antibody(左小图)和 Atg14 antibody(右小图)检测到的相应蛋白质印迹如下图所示。293T 细胞要么与表达 GFP 标记的人 Atg14 蛋白 (hAtg14-GFP) 和小鼠 ULK1 (mULK1) 的载体共转染,要么仅用表达 GFP 标记的人 Atg14 蛋白 (hAtg14-GFP) 的载体转染或转染空载,然后裂解。
