A structural study of the myristoylated N-terminus of ARF1
The effect of myristoylation on the 15-amino-acid peptide from the membrane-binding N-terminus of ADP ribosylation factor 1 (ARF1) was studied using neutron diffraction and circular dichroism. A previous study on the non-acylated form indicated that the peptide lies parallel to the membrane, at a shallow depth and in the vicinity of the ...

Ion Activation Methods for Top‐Down Proteomics
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Rab7 associates with early endosomes to mediate sorting and transport of Semliki forest virus to late endosomes. [PDF]
Semliki forest virus (SFV) is internalized by clathrin-mediated endocytosis, and transported via early endosomes to late endosomes and lysosomes. The intracellular pathway taken by individual fluorescently labeled SFV particles was followed using ...

Mutational Analysis of the Arf1•GTP/Arf GAP Interface Reveals an Arf1 Mutant that Selectively Affects the Arf GAP ASAP1 [PDF]
Arf1 is a GTP binding protein that functions at a number of cellular sites to control membrane traffic and actin remodeling. Arf1 is regulated by site-specific GTPase-activating proteins (GAPs). The combined results of crystallographic and biochemical studies have led to the proposal that Arf1 GAPs differ in the specific interface formed with Arf1.

Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

The small GTPase ARF6 regulates GABAergic synapse development
ADP ribosylation factors (ARFs) are a family of small GTPases composed of six members (ARF1–6) that control various cellular functions, including membrane trafficking and actin cytoskeletal rearrangement, in eukaryotic cells.

Abstract figure legend Maternal protein restriction (MPR) induced persistent renal histopathological alterations accompanied by elevated serum creatinine levels. Nephron‐segment proteomic analysis revealed region‐specific molecular dysregulation affecting Bowman's capsule (PARK7, oxidative stress sensor; MSN, cytoskeletal organization), the proximal ...

CLN3 deficient cells display defects in the ARF1-Cdc42 pathway and actin-dependent events.
Juvenile Batten disease (juvenile neuronal ceroid lipofuscinosis, JNCL) is a devastating neurodegenerative disease caused by mutations in CLN3, a protein of undefined function.

The Small GTPase Arf6 Functions as a Membrane Tether in a Chemically-Defined Reconstitution System
Arf-family small GTPases are essential protein components for membrane trafficking in all eukaryotic endomembrane systems, particularly during the formation of membrane-bound, coat protein complex-coated transport carriers.
