Function
ATG11_YEAST Involved in cytoplasm to vacuole transport (Cvt), pexophagy, mitophagy and nucleophagy. Recruits mitochondria for their selective degradation via autophagy (mitophagy) during starvation, through its interaction with ATG32. Works as scaffold proteins that recruit ATG proteins to the pre-autophagosome (PAS), the site of vesicle/autophagosome formation. Required for ATG9 anterograde transport from the mitochondria to the PAS. Recruits also the ATG19-prAPE1 complex to the PAS. Required for the Cvt vesicles completion. Plays a significant role in life span extension.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34]
