Biological function summary
ARF1 is essential in regulating membrane dynamics and vesicular traffic. It forms part of the COPI and clathrin-coated vesicle complexes where it recruits coat proteins to budding vesicles. This recruitment is fundamental for maintaining Golgi structure and function. Additionally ARF1 plays a role in cytokinesis by interacting with the septin cytoskeleton. The protein also influences actin cytoskeleton remodeling which is pivotal for cell shape changes and motility.
Pathways
ARF1 is central to both the endocytic and secretory pathways. It collaborates with proteins like ARFS and 3F1 in modulating the trafficking of cargo between the endoplasmic reticulum and Golgi. Within the secretory pathway ARF1 interacts with SNARE proteins to facilitate vesicle docking and fusion. Its actions in pathways maintain cellular homeostasis and promote proper cellular response to various stimuli.

General info
Function
Small GTPase involved in protein trafficking between different compartments (PubMed : 8253837). Modulates vesicle budding and uncoating within the Golgi complex (PubMed : 8253837). In its GTP-bound form, triggers the recruitment of coatomer proteins to the Golgi membrane (PubMed : 8253837). The hydrolysis of ARF1-bound GTP, which is mediated by ARFGAPs proteins, is required for dissociation of coat proteins from Golgi membranes and vesicles (PubMed : 8253837). The GTP-bound form interacts with PICK1 to limit PICK1-mediated inhibition of Arp2/3 complex activity; the function is linked to AMPA receptor (AMPAR) trafficking, regulation of synaptic plasticity of excitatory synapses and spine shrinkage during long-term depression (LTD) (By similarity). Plays a key role in the regulation of intestinal stem cells and gut microbiota, and is essential for maintaining intestinal homeostasis (By similarity). Plays also a critical role in mast cell expansion but not in mast cell maturation by facilitating optimal mTORC1 activation (By similarity).. (Microbial infection) Functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase.
Sequence similarities
Belongs to the small GTPase superfamily. Arf family.
Post-translational modifications
(Microbial infection) Demyristoylated by S.flexneri cysteine protease IpaJ which cleaves the peptide bond between N-myristoylated Gly-2 and Asn-3.
