However, CT or pentameric CTB may be endocytosed, depending on cell type, either through caveolin-coated vesicles, clathrin-coated vesicles or by the so-called Arf6
Genetic studies have implicated different ARFs in diverse growth processes including embryogenesis (ARF5/MONPTEROS, ARF17), root (ARF7/NPH4, ARF10, ARF16, ARF19) and floral development (ARF1, ARF2, ARF3/ETT1N, ARF6
, ARF8), and senescence (ARF2).
Microvesicle fission is due to myosin and actin cytoskeletal rearrangements regulated by the Ras-related GTPase ADP-ribosylation factor 6 (ARF6
) and its signaling cascade .
LincRNA-RoR-mediated downregulation of miR-145 led to upregulation of ARF6
(ADP-ribosylation factor 6), which is strongly involved in metastatic processes; indeed, ARF6
affected E-cadherin localization and impaired cell-cell adhesion, promoting cell invasion in TNBCs .

and ARF8 expression, and regulates both female and male reproduction," Development, vol.
Endocytosis of CT may follow one of three pathways: (i) lipid raft/caveolae mediated endocytic pathway, (ii) clathrin mediated endocytic pathway, or (iii) ADP-ribosylation factor 6 (Arf6
)-associated endocytic pathway.
