Subcellular location

Subcellular Location:
Cytoplasm, cytosol. Cell membrane; Peripheral membrane protein. Note=Translocates from the cytosol to membranes enriched in phosphatidylinositol 3,4,5-trisphosphate.

Function

Function:
Promotes guanine-nucleotide exchange on ARF1 and ARF6. Promotes the activation of ARF factors through replacement of GDP with GTP.
