General annotation (Comments)

Function	Activates the small GTPases ARF1, ARF5 and ARF6. Regulates the formation of post-Golgi vesicles and modulates constitutive secretion. Modulates phagocytosis mediated by Fc gamma receptor and ARF6. Modulates PXN recruitment to focal contacts and cell migration. Ref.3 Ref.4 Ref.5
Subunit structure	Binds PXN, ARF1, ARF5, ARF6, PTK2B and SRC.
Subcellular location	Cytoplasm. Golgi apparatus › Golgi stack membrane; Peripheral membrane protein. Cell membrane; Peripheral membrane protein. Note: Colocalizes with F-actin and ARF6 in phagocytic cups. Ref.3 Ref.4 Ref.5
Tissue specificity	Detected in heart, brain, placenta, kidney, monocytes and pancreas. Ref.3
Induction	Up-regulated during monocyte maturation.
Domain	The conserved Arg-464 in the Arf-GAP domain probably becomes part of the active site of bound small GTPases and is necessary for GTP hydrolysis.
Post-translational modification	Phosphorylated on tyrosine residues by SRC and PTK2B. Ref.3 Ref.6 Ref.7 Ref.8
Sequence similarities	Contains 2 ANK repeats. Contains 1 Arf-GAP domain. Contains 1 PH domain. Contains 1 SH3 domain.
