Taxonomic identifier

559292 [NCBI]

Taxonomic lineage

cellular organisms › Eukaryota › Opisthokonta › Fungi › Dikarya › Ascomycota › saccharomyceta › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces › Saccharomyces cerevisiae

Protein attributes

Sequence length	893 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in actin patch polarization. Required for maintaining a proper budding pattern in yeast cells. Required for proper polarized localization of the ADP-ribosylation factor ARF3 at the plasma membrane. Ref.8
Subunit structure	Interacts with ARF3 (in GTP-bound form). Interacts with CNM67. Ref.6 Ref.8
Subcellular location	Cytoplasm › perinuclear region. Cytoplasm › cell cortex. Note: Enriched at the nuclear envelope and at the plasma membrane, especially in daughter cells and at the bud neck. Ref.6 Ref.8
Induction	Mainly expressed in dividing cells, but not in stationary phase cells (at protein level). Ref.6 Ref.8
Miscellaneous	Present with 768 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the AFI1/mesA family.
Sequence caution	The sequence CAA60863.1 differs from that shown. Reason: Frameshift at positions 101 and 102.
