Taxonomic distribution

NCBITaxon:4932 Saccharomyces cerevisiae — COMMON: Budding-yeast Cvt vesicles are double-membrane carriers whose bounded lumen encloses cytoplasm-to-vacuole targeting cargo before vacuolar delivery. [DOI:10.1091/mbc.e03-07-0479]

NCBITaxon:4932 Saccharomyces cerevisiae — Budding-yeast model used to characterize Cvt vesicle assembly and its early-secretory-pathway requirements. [DOI:10.1091/mbc.e03-07-0479]

A Cvt vesicle membrane bounds the Cvt vesicle lumen inside the completed double-membrane Cvt vesicle.

Subject	Predicate	Object	Evidence
Cvt vesicle lumen	is part of	Cvt vesicle	`uniprot.location:SL-0323` — Cvt vesicle lumen UniProt SL-0323 places the Cvt vesicle lumen under the Cvt vesicle. `GO:0033107` GO:0033107 identifies the enclosing Cvt vesicle.
Cvt vesicle membrane	bounds	Cvt vesicle lumen	`uniprot.location:SL-0323` — Cvt vesicle lumen UniProt SL-0323 describes the lumen as bounded by the Cvt vesicle membrane. `GO:0033110` GO:0033110 identifies either bilayer surrounding a Cvt vesicle.

uniprot.location:SL-0323 — Cvt vesicle lumen UniProt Subcellular Location entry SL-0323 identifies the Cvt vesicle lumen, places it under cytoplasmic vesicle lumen, and names it part of Cvt vesicle.
