General annotation (Comments)

Function

Guanine nucleotide exchange factor for RAB8A. Mediates the release of GDP from RAB8A 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

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. Cytoplasmcytoskeletonactin patch. Cell projectionlamellipodium. 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. 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.

Binary interactions
