GTP: gatekeeper for autophagy.

Abstract:

:Chaperone-mediated autophagy (CMA) is involved in cellular quality control, and in the response to stress, deterioration in CMA contributes to the aging phenotype and to various disorders. The paper by Bandyopadhyay et al. in this issue of Molecular Cell demonstrates the role of GTP binding by elongation factor 1 alpha (EF1alpha) in regulating the lysosomal uptake of CMA substrates.

  • Atg8 transfer from Atg7 to Atg3: a distinctive E1-E2 architecture and mechanism in the autophagy pathway.

    abstract::Atg7 is a noncanonical, homodimeric E1 enzyme that interacts with the noncanonical E2 enzyme, Atg3, to mediate conjugation of the ubiquitin-like protein (UBL) Atg8 during autophagy. Here we report that the unique N-terminal domain of Atg7 (Atg7(NTD)) recruits a unique "flexible region" from Atg3 (Atg3(FR)). The struct...
