    Protein IVY1
Alternative name(s):
    Interaction with VPS33 and YPT7 protein 1

Gene names

Name:	IVY1
Ordered Locus Names:	YDR229W
ORF Names:	YD9934.14

Organism

Saccharomyces cerevisiae (Baker's yeast) [Complete proteome]

Taxonomic identifier

4932 [NCBI]

Taxonomic lineage

Eukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length	453 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May be required for vacuolar fusion. Overexpression leads to fragmentation of vacuoles, missorting of the vacuolar enzyme carboxypeptidase Y (CPY) to the exterior of the cell and accumulation of multivesicular bodies inside the cell. Ref.2
Subunit structure	Homomultimer. Interacts with YPT7 and VPS33. Ref.2
Subcellular location	Vacuole membrane; Peripheral membrane protein. Note: Binds to various phospholipids. Ref.2
Miscellaneous	Present with 2840 molecules/cell in log phase SD medium. Ref.3
