In yeast, the t-SNAREs Sec9p and Sso2p are required for exocytosis and promote tubulovesicular budding of Atg9 positive vesicles, which are also required for autophagosome biogenesis.
Nos lévedos, son necesarios os t-SNAREs Sec9p e Sso2p para a exocitose e promoven a evaxinación tubulovesicular de vesiculas Atg9 positivas, que se requiren tamén para a bioxénese de autofagosomas.
