Target

  • Function

    May be involved in vesicular trafficking and neurotransmitter release. Together with RAB11A, RAB3IP, 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. Together with MYO5B and RAB11A participates in epithelial cell polarization.
  • Sequence similarities

    Belongs to the small GTPase superfamily. Rab family.
  • Cellular localization

    Cell membrane. Golgi apparatus. Cytoplasm > perinuclear region. Cell projection. Colocalizes with OPTN at the Golgi complex and in vesicular structures close to the plasma membrane. In the GDP-bound form, present in the perinuclear region. Shows a polarized distribution to distal regions of cell protrusions in the GTP-bound form. Colocalizes with PARD3, PRKCI, EXOC5, OCLN, PODXL and RAB11A in apical membrane initiation sites (AMIS) during the generation of apical surface and luminogenesis.

    Dilution buffer: 5% BSA/TBST.

    The LRRK2 pathogenic mutation Y1699C increases LRRK2 activity and markedly elevates Rab8 phosphorylation in MEF (mouse embryonic fibroblasts).

    The results show that this antibody recognizes other LRRK2-phosphorylated Rab proteins (Rab3A, Rab10, and Rab35). The phospho-threonine site in Rab8 (T72) differs from that of Rab3A (T86); Rab10 (T73); and Rab43 (T82).

    The images were kindly provided by our collaborator, Dr. Dario Alessi, and have been published (PMID: 29127256).
