Mechanisms of autophagy in metabolic stress response

AS Gross, M Graef - Journal of molecular biology, 2020 - Elsevier
Autophagy is a highly conserved catabolic pathway critical for stress responses and the
maintenance of cellular homeostasis. Defective autophagy contributes to the etiology of an …

Endoplasmic reticulum-associated mitochondria–cortex tether functions in the distribution and inheritance of mitochondria

LL Lackner, H Ping, M Graef… - Proceedings of the …, 2013 - National Acad Sciences
To elucidate the functional roles of mitochondrial dynamics in vivo, we identified genes that
become essential in cells lacking the dynamin-related proteins Fzo1 and Dnm1, which are …

Parallel phospholipid transfer by Vps13 and Atg2 determines autophagosome biogenesis dynamics

R Dabrowski, S Tulli, M Graef - Journal of Cell Biology, 2023 - rupress.org
During autophagy, rapid membrane assembly expands small phagophores into large
