IMPA1 Protein, Human, Recombinant (His Tag)

IMPA1 (Inositol Monophosphatase 1) is a Protein Coding gene. This gene encodes an enzyme that dephosphorylates Myo-inositol monophosphate to generate free Myo-inositol, a precursor of phosphatidylinositol, and is, therefore, an important modulator of intracellular signal transduction via the production of the second messenger's myoinositol 1,4,5-trisphosphate and diacylglycerol. Despite its many physiological functions, no clinical phenotype has been assigned to this gene dysfunction to date. Additionally, IMPA1 is the main target of lithium, a drug that is at the forefront of treatment for bipolar disorder. IMPA1 is widely expressed in the testis, thyroid, and other tissues. Diseases associated with IMPA1 include Mental Retardation, Autosomal Recessive 59, and Bipolar Disorder.

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 PBS, 10 % 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 IMPA1 consists of 295 amino acids and predicts a molecular mass of 32.4 KDa. It migrates as an approximately 32 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.
