Recombinant Human Rab-3A-interacting protein (RAB3IP)

Uniprot Id

Q96QF0

Target Species

Human

Target Name

RAB3IP

Target Full Name

Rab-3A-interacting protein

Target 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.

Target Subcellular Location

Cytoplasm. Nucleus. Cytoplasm, cytoskeleton. Cell projection, lamellipodium. Vesicle. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome.

Target Protein Families

SEC2 family

Target Tissue Specificity

Expressed in brain, kidney, heart, pancreas and placenta. Not detected in skeletal muscle or liver.

Target Background

Enables guanyl-nucleotide exchange factor activity and identical protein binding activity. Involved in cilium assembly; protein localization to organelle; and protein targeting to membrane. Located in centrosome; cytosol; and nucleus.
