Summary: The protein encoded by this gene belongs to the ARL (ADP-ribosylation factor-like) family of proteins, which are structurally related to ADP-ribosylation factors (ARFs). ARFs, described as activators of cholera toxin (CT) ADP-ribosyltransferase activity, regulate intracellular vesicular membrane trafficking, and stimulate a phospholipase D (PLD) isoform. Although, ARL proteins were initially thought not to activate CT or PLD, later work showed that they are weak stimulators of PLD and CT in a phospholipid dependent manner. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

ArfGAP1 acts as a GTPase-activating protein for human ADP-ribosylation factor-like 1 protein.
Title: ArfGAP1 acts as a GTPase-activating protein for human ADP-ribosylation factor-like 1 protein.
The ARFRP1 functions upstream of two other ARL GTPases, ARL1 and ARL5, which in turn recruit golgins and GARP, respectively, to the trans-Golgi network (TGN).
Title: ARFRP1 functions upstream of ARL1 and ARL5 to coordinate recruitment of distinct tethering factors to the trans-Golgi network.
Plasticity allows Arl1 to interact with different effectors of unrelated structure.
Title: Structural Insights into Arl1-Mediated Targeting of the Arf-GEF BIG1 to the trans-Golgi.
Together the findings indicate that Arl1 links Rab4-dependent formation of endosomal sorting domains with downstream assembly of adaptor protein complexes that constitute the endosomal sorting machinery.
Title: Rab4 orchestrates a small GTPase cascade for recruitment of adaptor proteins to early endosomes.
results demonstrate that activated Arl1p can promote the spatial modulation of membrane organization at the trans-Golgi network through interacting with the effectors Gea2p and Drs2p
Title: Arl1p regulates spatial membrane organization at the trans-Golgi network through interaction with Arf-GEF Gea2p and flippase Drs2p.
The Arl1.Arfaptin-2 BAR structure suggests that one of the two Arl1 molecules competes with Rac1, which binds to the concave face of the Arfaptin-2 BAR homodimer and may hinder its membrane association.
Title: Structural basis for membrane binding specificity of the Bin/Amphiphysin/Rvs (BAR) domain of Arfaptin-2 determined by Arl1 GTPase.
arfaptins are recruited onto trans-Golgi membranes by interacting with Arl1, and capable of inducing membrane deformation via their BAR domains.
Title: Arfaptins are localized to the trans-Golgi by interaction with Arl1, but not Arfs.
Study demonstrates that Golgi recruitment of endogenous GCC185 does not involve Rab6A/A' and Arl1.
Title: The localization of the Golgin GCC185 is independent of Rab6A/A' and Arl1.
Results show that ARL1 and ARFRP1 regulate retrograde transport of Shiga toxin to the TGN and anterograde transport of VSVG from the TGN, respectively.
Title: Differential effects of depletion of ARL1 and ARFRP1 on membrane trafficking between the trans-Golgi network and endosomes.
Data show that Arl1 regulates the membrane recruitment of Golgin-97, which plays a role in transport from the endosome to the trans-Golgi network.
Title: Autoantigen Golgin-97, an effector of Arl1 GTPase, participates in traffic from the endosome to the trans-golgi network.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
