Atg9A Protein, an Autophagy-related Membrane Protein, Is Localized in the Neurons of Mouse Brains
Abstract
Old and unneeded intracellular macromolecules are delivered through autophagy to lysosomes that degrade macromolecules into bioactive monomers such as amino acids. Autophagy is conserved in eukaryotes and is essential for the maintenance of cellular metabolism. Currently, more than 30 autophagy-related genes (Atgs) have been identified in yeast. Of these genes, the 18 that are essential for autophagosome formation are also conserved in mammalian cells. Atg9 is the only transmembrane Atg protein required for autophagosome formation. Although the subcellular localization of the Atg9A protein (Atg9Ap) has been examined, little is known about its precise cell and tissue distribution. To determine this, we produced an antibody specific to mouse Atg9Ap. The antibody recognized both non-glycosylated and glycosylated Atg9Ap, which have molecular masses of ×94 kDa and 105 kDa, respectively. Although Atg9Ap was ubiquitously detected, it was highly expressed in neurons of the central nervous system. In Purkinje cells, Atg9Ap immunoreactivity was localized in the endoplasmic reticulum (ER), trans-Golgi network (TGN), lysosomes/late endosomes, and in axon terminals. These results suggest that Atg9Ap may be involved in autophagosome formation in the ER and axon terminals of neurons, the TGN, and lysosomes/late endosomes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
