Purity: > 90 % by SDS - PAGE Format: Liquid. In 20mM Tris buffer (pH 8.0) containing 10% glycerol, 1mM DTT, 0.1M NaCl. . RAB6A belongs to the small GTPase superfamily. It may be involved in protein transport. It is a regulator of membrane traffic from the Golgi apparatus towards the endoplasmic reticulum (ER) and has a low GTPase activity. Recombinant human RAB6A protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
