Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

The recombinant Human APBA2 protein is made by following sequential steps: inserting a DNA fragment encoding the Human APBA2 protein (1-749aa) into a plasmid vector, transferring this vector into mammalian cells, selecting the positive cells, culturing positive cells, inducing the protein expression, and collecting the APBA2 protein. The protein features a N-terminal 10xHis tag and C-terminal Myc tag fusion. The recombinant APBA2 protein is subjected to affinity purification and SDS-PAGE analysis. Its purity is over 85%.

Target Background

Function
Putative function in synaptic vesicle exocytosis by binding to STXBP1, an essential component of the synaptic vesicle exocytotic machinery. May modulate processing of the amyloid-beta precursor protein (APP) and hence formation of APP-beta.

  5. The co-occurrence of two nonsynonymous mutations in both affected siblings in a single family, each transmitted from a different unaffected parent, suggest a role for APBA2 mutations in rare individuals with ASD. PMID: 20029827
  6. APBA2 were genes activated in early endometrial endometrioid carcinoma (stages I-II). PMID: 20015385
  7. X11beta-mediated reduction in cerebral Abeta is associated with cognition and long-term potentiation in Alzheimer's disease APPswe transgenic mice. PMID: 19744962
  8. Interaction of transcriptional coactivators with Mint1 or Mint2 prevents nuclear localization and transactivation of the transduction network mediated by amyloid precursor protein. PMID: 20016085
  9. The APBA2 gene has been found to map to a more telomeric location in chromosome 15q13 than previously found, and is partially duplicated within the broader region located approximately 5 Mb distal to the intact locus. PMID: 12720574
  10. hXB51 isoforms regulate Abeta generation differently, either enhancing it by modifying the association of X11L with APP or suppressing it in an X11L-independent manner PMID: 12780348
  11. This protein, which is a member of the mammalian LIN-10 protein family and a possible regulator of Abeta production, elevated APP and APLP2 phosphorylation PMID: 14970211
  12. Comparative genome hybridization suggests a role for NRXN1 and APBA2 in schizophrenia. PMID: 17989066
  13. Phosphorylation of amino acids Ser236 and Ser238 in the X11L regulatory region are critical for increasing association of X11L and amyloid beta-protein precursor and are conserved in X11, a neuronal X11 family protein, but not in non-neuronal X11L2. PMID: 19222704
