Rab4GST-His Ras-associated, small GTP-binding protein human, recombinant, E. coli

Rab4 is a small GTPase that belongs to the Ras superfamily. Rab proteins play an important role in various aspects of membrane traffic, including cargo selection, vesicle budding, vesicle motility, tethering, docking, and fusion. The monomeric GTPase Rab4 is associated with early endosomes and regulates recycling vesicle formation. Together with Rab5 it act to control influx and efflux out of early endosomes. The GST-Tag facilitates the protein`s application in typical GST pull-down assays.
