Post Translational Modifications | Ubiquitinated by SCF(FBXW11) E3 ubiquitin-protein ligase complex. Ubiquitination induces proteasomal degradation. |
Function | Promotes guanine-nucleotide exchange on ARF1, ARF5 and ARF6. Promotes the activation of ARF factors through replacement of GDP with GTP. Plays an important role in membrane trafficking, during junctional remodeling and epithelial polarization, through regulation of ARF6 activity. |
