ERH Protein, Human, Recombinant (His Tag)

ERH (enhancer of rudimentary homolog) belongs to the E (R) family. It is expressed in all tissues examined. The monomeric structure of ERH comprises a single domain consisting of three α-helices and four β-strands, which is a novel fold. In the crystal structure, ERH assumes a dimeric structure, through interactions between the β-sheet regions. The formation of an ERH dimer is consistent with the results of analytical ultracentrifugation. ERH may have a role in the cell cycle. The Drosophila protein ERH is a small protein of 14 amino acids. It has been found to be an enhancer of the rudimentary gene, involved in pyrimidine biosynthesis. From an evolutionary point of view, ERH is highly conserved and has been found to exist in probably all multicellular eukaryotic organisms. ERH interacts with POLDIP3.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile 20mMTris, 0.1M NaCl, 1mM DTT, 20% glycerol pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant human ERH consists of 119 amino acids and predicts a molecular mass of 14.1 KDa. It migrates as an approximately 14 KDa band in SDS-PAGE under reducing conditions.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
