NRBF2 Protein, Human, Recombinant (His & GST Tag)

NRBF2 (Nuclear Receptor Binding Factor 2) is a Protein Coding gene. The encoded protein may modulate transcriptional activation by target nuclear receptors. It is widely expressed in the appendix, placenta, and other tissues. NRBF2/Atg38 has been identified as the fifth subunit of the macroautophagy/autophagy class III phosphatidylinositol 3-kinase (PtdIns3K) complex, along with ATG14/Barkor, BECN1/Vps30, PIK3R4/p150/Vps15, and PIK3C3/Vps34. NRBF2 is a critical molecular switch of PtdIns3K and autophagy activation, and its on/off state is precisely controlled by MTORC1 through phosphorylation. NRBF2, a key component, and regulator of the PtdIns3K has been involved in APP-CTFs homeostasis in Alzheimer's disease (AD) cell models. NRBF2 plays an important role in regulating the degradation of APP-CTFs through modulating autophagy.

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 20mM Tris, 500mM NaCl, 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 NRBF2/GST chimera consists of 524 amino acids and has a calculated molecular mass of 60.2 kDa. The recombinant protein migrates as an approximately 61 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.
