Comparison of [L8K]Arf1 crystal structure with human and yeast Arf1 structures.

open access: yes
(A) Crystal structure of [L8K]Arf1 in complex with guanosine-3’-monophosphate-5’-diphosphate (G3D). N- and C-termini, G domain motifs, and magnesium ion are labeled. Part of switch II could not be modeled and is depicted with dashed lines.

ARF1-GTP is reduced in CLN3-null MBECs.

open access: yes, 2014
(A) ARF1-GTP levels were quantified in Cln3R and Cln3−/− MBEC lysates. (B) Total ARF1 protein levels were quantified in Cln3R and Cln3−/− MBEC lysates by western blot, expressed as band intensity normalized to the actin loading control.

Point mutations in Arf1 reveal cooperative effects of the N-terminal extension and myristate for GTPase-activating protein catalytic activity.

open access: yesPLoS ONE
The ADP-ribosylation factors (Arfs) constitute a family of small GTPases within the Ras superfamily, with a distinguishing structural feature of a hypervariable N-terminal extension of the G domain modified with myristate.

Parvovirus B19 and Human Parvovirus 4 Encode Similar Proteins in a Reading Frame Overlapping the VP1 Capsid Gene

open access: yesViruses
Viruses frequently contain overlapping genes, which encode functionally unrelated proteins from the same DNA or RNA region but in different reading frames. Yet, overlapping genes are often overlooked during genome annotation, in particular in DNA viruses.

The exploration of ARF1 screening assays to determine the drug status of ARF1 in cancer and malaria

open access: yes, 2020
ARF GTPases are key regulators of the secretory and endocytic pathways. ARF1 is involved in the secretory pathway. ARF1 has been implicated in the endoplasmic reticulum to Golgi transport, function of the Golgi apparatus and transport from the trans ...

Examination of how the Arf1 G domain hydrophobic cavity is occupied by the N-terminal extension in Arf1 structures.

open access: yes
(A) Comparison of the positions of residues within the N-terminal extensions of non-myristoylated WT Arf1•GDP (left) and [L8K]Arf1•G3D (middle). An overlay of the two structures is shown on the right, with arbitrary labels for the positions of the amino ...

ArfGAP1 generates an Arf1 gradient on continuous lipid membranes displaying flat and curved regions.

open access: yes, 2010
International audienceArfGAP1, which promotes GTP hydrolysis on the small G protein Arf1 on Golgi membranes, interacts preferentially with positively curved membranes through its amphipathic lipid packing sensor (ALPS) motifs.

Exploring the role of ADP-ribosylation factor 1 (Arf1) in tunneling nanotube formation

open access: yes, 2023
Tunneling nanotubes (TNTs) are cellular protrusions used for direct communication and transfer of material between cells. However, numerous infectious agents like HIV, COVID-19, and prions are known to spread using TNTs, so inhibiting TNT formation could
