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).

    Figure 1. Co-transfection of 293T cells with constructs expressing human Atg14 and mouse ULK1 increases phosphorylation of Atg14 at Ser29 compared to cells transfected with only an Atg14 expression construct, but does not affect the level of total Atg14. Atg14 is also highly expressed in 293T cells transfected with an Atg14 expression construct compared to mock transfected cells. The relationship between lysate protein concentration from Atg14/ULK1 co-transfected, Atg14-only transfected, and mock transfected 293T cells and the absorbance at 450 nm using the PathScan® RP Total Atg14 Sandwich ELISA Kit #26160 is shown in the upper figure. The corresponding western blots using phospho-Atg14 (Ser29) antibody (left panel) and Atg14 antibody (right panel) are shown in the lower figure. 293T cells were co-transfected with constructs expressing GFP-tagged human Atg14 protein (hAtg14-GFP) and mouse ULK1 (mULK1), just transfected with a construct expressing GFP-tagged human Atg14 protein (hAtg14-GFP), or mock transfected, and then lysed.
