|WB||1/1000. Predicted molecular weight: 47 kDa.|
|IP||Use at an assay dependent dilution.|
FunctionActs 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.
Sequence similaritiesContains 1 PH domain.
Contains 1 SEC7 domain.
DomainThe PH domain is necessary and sufficient for plasma membrane relocalization.
Cellular localizationCell membrane. Cytoplasm. Both isoform 1 and isoform 2 are recruited to the cell membrane through its association with ARL4A, ARL4C and ARL4D. Requires also interaction with phosphoinositides for targeting to plasma membrane.
