|Other Names||ADP-ribosylation factor-like protein 2, ARL2|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP2305a was selected from the N-term region of human ARL2 . A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||The synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml deionized water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Small GTP-binding protein which cycles between an inactive GDP-bound and an active GTP-bound form, and the rate of cycling is regulated by guanine nucleotide exchange factors (GEF) and GTPase-activating proteins (GAP). GTP-binding protein that does not act as an allosteric activator of the cholera toxin catalytic subunit. Regulates formation of new microtubules and centrosome integrity. Prevents the TBCD-induced microtubule destruction. Participates in association with TBCD, in the disassembly of the apical junction complexes. Antagonizes the effect of TBCD on epithelial cell detachment and tight and adherens junctions disassembly. Together with ARL2, plays a role in the nuclear translocation, retention and transcriptional activity of STAT3. Component of a regulated secretory pathway involved in Ca(2+)-dependent release of acetylcholine. Required for normal progress through the cell cycle.|
|Cellular Location||Mitochondrion intermembrane space. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Nucleus. Cytoplasm. Note=The complex formed with ARL2BP, ARL2 and SLC25A6 is expressed in mitochondria. The complex formed with ARL2BP, ARL2 and SLC25A4 is expressed in mitochondria (By similarity). Not detected in the Golgi, nucleus and on the mitotic spindle. Centrosome-associated throughout the cell cycle Not detected to interphase microtubules.|

ADP-ribosylation factors (ARFs) regulate intracellular vesicular membrane trafficking and stimulate a phospholipase D isoform. ARL (ADP-ribosylation like factor) proteins are very similar in sequence to ARFs. ARFs and ARF-like (ARL) proteins, which share sequence similarity with ARFs, form a subfamily of the Ras-related GTPase superfamily. ARL2 encodes a ubiquitiously expressed 184-amino acid predicted protein that is 76% identical to ARF1 and 40 to 45% identical to the Drosophila ARL proteins. Recombinant ARL2 binds to GTP rapidly but guanine nucleotide exchange does not require phospholipids, which is a characteristic of the ARF proteins.
