Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 10% glycerol. ASNA1, also as known as ARSA and TRC40, belongs to the arsA ATPase family. ASNA1 is the human homolog of the bacterial arsA gene. In E.coli, ArsA ATPase is the catalytic component of a multisubunit oxyanion pump that is responsible for resistance to arsenicals and antimonials. ATPase required for the post-translational delivery of tail-anchored (TA) proteins to the endoplasmic reticulum. Recombinant human ASNA1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
