Control of autophagy initiation by phosphoinositide 3‐phosphatase jumpy
Open accessAbstract
The majority of studies on autophagy, a cytoplasmic homeostasis pathway of broad biological and medical significance, have been hitherto focused on the phosphatidylinositol 3-kinases as the regulators of autophagy. Here, we addressed the reverse process driven by phosphoinositide phosphatases and uncovered a key negative regulatory role in autophagy of a phosphatidylinositol 3-phosphate (PI3P) phosphatase Jumpy (MTMR14). Jumpy associated with autophagic isolation membranes and early autophagosomes, defined by the key factor Atg16 necessary for proper localization and development of autophagic organelles. Jumpy orchestrated orderly succession of Atg factors by controlling recruitment to autophagic membranes of the sole mammalian Atg factor that interacts with PI3P, WIPI-1 (Atg18), and by affecting the distribution of Atg9 and LC3, the two Atg factors controlling organization and growth of autophagic membranes. A catalytically inactive Jumpy mutant, R336Q, found in congenital disease centronuclear myopathy, lost the ability to negatively regulate autophagy. This work reports for the first time that initiation of autophagy is controlled not only by the forward reaction of generating PI3P through a lipid kinase but that its levels are controlled by a specific PI3P phosphatase, which when defective can lead to human disease.

In the citing paper
“Furthermore, mounting evidence shows that autophagy is regulated by distinct mechanisms in different cell types [11–26], and these cell type-specific mechanisms underlie the differential vulnerability of separate tissues to autophagy mutations, resulting in heterogenous manifestations of disease.”

Experimental — accuracy not yet measuredIn the citing paper
“For instance, centronuclear myopathy is caused by mutations in the genes encoding MTM1 (myotubularin1) or MTMR14/Jumpy (myotubularin related protein 14) [17,20].”

In the citing paper
“These loss-of-function mutations prevent these enzymes from metabolizing phosphoinositides required for autophagy, thereby disinhibiting autophagy flux and muscle atrophy [17,20].”

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.
