Product information

Member of the ARF family of GTPases within the superfamily of Ras-like GTPases. Similar to most GTPases, Arf6 cycles between GDP- and GTP-bound states; the GTP-bound form engages a set of diverse effectors to regulate cell processes. In particular, Arf6 N-terminal His6-tagged regulates actin organization as well as endocytosis. Nucleotide cycling is regulated by guanine nucleotide exchange factors (GEFs), guanine dissociation inhibitors (GDIs) and GTPase activating proteins (GAPs).1,2

Protein is > 98% pure as determined by densitometry of the final sample submitted to SDS-PAGE and stained with Coomassie blue (Fig. 1). Arf6 was heterologously expressed in E. coli as a histidine-tagged protein and purified by a combination of affinity, ion exchange, and gel exclusion chromatographies. The histidine-tagged was not removed leaving a (His)6-Gly-Gly tag at the N-terminus followed by residues 1-175 of human Arf6.
