Selective autophagy relies on adaptor proteins to bind and transport cargos (or substrates) to the lysosome or vacuole, yet the mechanisms for cargo recognition are not well understood. In this issue, Wang et al (2021) showed that in the fission yeast, Nbr1, a homolog of a mammalian selective autophagy adaptor, recognizes vacuolar hydrolases Ams1 and Ape4 through both versatile and cargo-specific interactions with the Nbr1 ZZ1 domain.
选择性自噬依赖衔接蛋白将货物(或底物)结合并运输到溶酶体或液泡中,但货物识别的机制尚不清楚。在本期杂志中,Wang 等人(2021)表明,在裂殖酵母中,Nbr1 是一种哺乳动物选择性自噬衔接蛋白的同源物,通过与 Nbr1 ZZ1 结构域的通用和货物特异性相互作用识别液泡水解酶 Ams1 和 Ape4。
