General annotation (Comments)
| Function | Guanine nucleotide exchange factor (GEF) which may activate RAB8A and RAB8B. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. Mediates the release of GDP from RAB8A and RAB8B but not from RAB3A or RAB5. Modulates actin organization and promotes polarized transport of RAB8A-specific vesicles to the cell surface. Together with RAB11A, RAB8A, the exocyst complex, PARD3, PRKCI, ANXA2, CDC42 and DNMBP promotes transcytosis of PODXL to the apical membrane initiation sites (AMIS), apical surface formation and lumenogenesis. Ref.2 Ref.9 Ref.10 |
| Subunit structure | Interacts with the N-terminal region of SSX2. Interacts with the GDP-bound forms of RAB3A, RAB3D, RAB8A and RAB8B. Ref.1 Ref.2 UniProtKB Q62739 |
| Subcellular location | Cytoplasm. Nucleus. Cytoplasm › cytoskeleton. Cell projection › lamellipodium. Note: Predominantly cytoplasmic but a small proportion colocalizes with SSX2 in the nucleus. Activation of protein kinase C results in redistribution to the periphery of lamellipodia. In the cytoskeleton, localizes to cortical actin. Ref.1 Ref.2 |
| Tissue specificity | Expressed in brain, kidney, heart, pancreas and placenta. Not detected in skeletal muscle or liver. Ref.1 Ref.2 |
| Sequence similarities | Belongs to the SEC2 family. |
