ARF1

Official Full Name
ADP-ribosylation factor 1
-
Overview
ADP-ribosylation factor 1 (ARF1) is a member of the human ARF gene family. The family members encode small guanine nucleotide-binding proteins that stimulate the ADP-ribosyltransferase activity of cholera toxin and play a role in vesicular trafficking as activators of phospholipase D. The gene products, including 6 ARF proteins and 11 ARF-like proteins, constitute a family of the RAS superfamily. The ARF proteins are categorized as class I (ARF1, ARF2 and ARF3), class II (ARF4 and ARF5) and class III (ARF6), and members of each class share a common gene organization. The ARF1 protein is localized to the Golgi apparatus and has a central role in intra-Golgi transport. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene. -

Q&As (21)
Ask a questionYes, ARF1 can undergo various post-translational modifications, including phosphorylation, acetylation, and lipidation. These modifications can affect its activity, localization, and interactions with other proteins, providing a means of regulation and modulation in response to cellular cues and signaling events.
Dysregulation of ARF1 has been observed in some cancers, where it can contribute to abnormal membrane trafficking and facilitate tumor cell proliferation, invasion, and metastasis. Targeting ARF1 and its associated pathways may hold therapeutic potential in cancer treatment.
ARF1 regulates membrane trafficking pathways, including protein sorting, vesicle formation, and transport between organelles such as the Golgi apparatus, plasma membrane, and endosomes.
Yes, ARF1 is involved in various neuronal processes, including axonal development, synapse formation, and neurotransmitter release. It regulates the trafficking and recycling of synaptic vesicles, ensuring the proper function of neuronal communication.
Yes, ARF1 and its regulators are potential targets for therapeutic intervention in diseases involving abnormal membrane trafficking, such as cancer and neurodegenerative disorders. Modulating ARF1 activity could potentially impact these processes.
