Arl3-Arl1 cascade acts on the cytoplasm-to-vacuole targeting pathway via dynamic nucleotide binding
Title: The Arl3 and Arl1 GTPases co-operate with Cog8 to regulate selective autophagy via Atg9 trafficking.
Through this screen, we were able to confirm several membrane traffic and autophagy regulators that have novel relationships with Arl1 and Ypt6 during autophagy
Title: A High Copy Suppressor Screen for Autophagy Defects in Saccharomyces arl1Δ and ypt6Δ Strains.
Hac1p restored the Golgi localization of Arl1p inIRE1-deleted cells. Ire1p-Hac1p axis regulated Syt1p phosphorylation, which enhances Arl1p activation, recruitment of Imh1p to the Golgi, and Syt1p interaction with Arl1p.
Title: Unfolded protein response regulates yeast small GTPase Arl1p activation at late Golgi via phosphorylation of Arf GEF Syt1p.
Imh1p and Drs2p modulate the activity of Gcs1p by timing its interaction with Arl1p, hence providing feedback regulation of Arl1p activity.
Title: Mechanism of action of the flippase Drs2p in modulating GTP hydrolysis of Arl1p.
The authors demonstrated that MON2 is a negative regulator of the GTP-restricted allele of ARL1 , ARL1[Q72L].
Title: Mon2 is a negative regulator of the monomeric G protein, Arl1.
results suggest partially overlapping functions of the GTPases in resistance to various stress factors, with Ypt6 being more efficient under physiological conditions and Arl1 more versatile when overexpressed
Title: Comparison of the influence of small GTPases Arl1 and Ypt6 on yeast cells' tolerance to various stress factors.
gene deletions affecting the Arl1 vesicle-tethering pathways prevent Arl1 activation and membrane localization
Title: Dysregulated Arl1, a regulator of post-Golgi vesicle tethering, can inhibit endosomal transport and cell proliferation in yeast.
The authors conclude that Arl1p, Kha1p and Nhx1p collaborate in survival strategies at nonoptimal pH, temperatures and cation concentrations, but work independent of each other.
Title: Genetic interactions among the Arl1 GTPase and intracellular Na(+) /H(+) antiporters in pH homeostasis and cation detoxification.
Findings reveal that activation of Arl1p is regulated in part by Syt1p, and imply that Arl1p activation, by using more than one GEF, exerts distinct biological activities at the Golgi compartment.
Title: Syt1p promotes activation of Arl1p at the late Golgi to recruit Imh1p.
Data show that Dop1p localizes to endosomes and exists in a complex with Neo1p-Ysl2p-Arl1p.
Title: Oligomeric Dop1p is part of the endosomal Neo1p-Ysl2p-Arl1p membrane remodeling complex.
