Protein Structure
UniProt Annotation
Function Acts as a guanine-nucleotide exchange factor (GEF). Promotes guanine-nucleotide exchange on ARF1, ARF3 and ARF6. Promotes the activation of ARF factors through replacement of GDP with GTP. The cell membrane form, in association with ARL4 proteins, recruits ARF6 to the plasma membrane. {ECO:0000269PubMed:17398095}.
Subcellular Localization Cell membrane {ECO:0000269PubMed:17398095}; Peripheral membrane protein {ECO:0000269PubMed:17398095}. Cytoplasm {ECO:0000269PubMed:17398095}. Note=Both isoform 1 and isoform 2 are recruited to the cell membrane through their association with ARL4A, ARL4C and ARL4D. They require also interaction with phosphoinositides for targeting to the plasma membrane.
