High impact information on ATG11

We propose that a pool of Atg11 mediates the anterograde transport of Atg9 to the PAS that is dependent on the actin cytoskeleton during yeast vegetative growth [1].
We also demonstrate that the integrity of the actin cytoskeleton is essential for correct targeting of Atg11 to the PAS [1].
We show that Atg11 governs Atg9 cycling through the PAS during specific autophagy [1].
Cvt9 oligomers peripherally associate with a novel, perivacuolar membrane compartment and interact with Apg1, a Ser/Thr kinase essential for both the Cvt pathway and autophagy [2].
Cvt9/Gsa9 functions in sequestering selective cytosolic cargo destined for the vacuole [2].

Anatomical context of ATG11

The deletion of CVT9 destabilizes the binding of prAPI to the membrane and analysis of a cvt9 temperature-sensitive mutant supports a direct role of Cvt9 in transport vesicle formation [2].
Nevertheless, Atg11, a protein that links receptor-bound cargo (peroxisomes, the Cvt complex) to the autophagic machinery was identified in all yeast species and filamentous fungi under study [3].

Associations of ATG11 with chemical compounds

Atg11 Directs Autophagosome Cargoes to the PAS Along Actin Cables [4].

Other interactions of ATG11

Accordingly, the deletion of APE1, ATG19, or ATG11 affected the formation of Cvt vesicles [5].
In particular, those factors are essential to correctly target the prApe1-Cvt19-Cvt9 complex to the preautophagosomal structure, the site of Cvt vesicle formation [6].
