Tag Info
The following tags are available.
N-terminal His-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
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 before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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℃/-80℃. 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
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel.
Gene References into Functions
  1. GABRA4 is associated with autism spectrum disorder in a dataset from Argentina. PMID: 26239769
  2. The ability of neurosteroids to modulate the phosphorylation and membrane insertion of alpha4 subunit-containing GABAARs may underlie the profound effects these endogenous signaling molecules have on neuronal excitability and behavior. PMID: 24778259
  3. Transgenic mice with the alpha4betadelta GABAA receptor subunit deletion show increased conditioned place preference, but not from delta-deficient or alpha4-deficient knockout mice. PMID: 24431441
  4. The pathway by which GABRA2 initially confers risk for eventual alcohol problems begins with a predisposition to sensation-seeking early in adolescence. PMID: 23561058
  5. Association between premenstrual symptom severity and two genes from the gamma-aminobutyric acid (GABA) pathway: steroid-5-alpha-reductase, alpha polypeptide 1 (SRD5A1) and gamma-aminobutyric acid receptor subunit alpha-4 (GABRA4). PMID: 22273344
  6. single nucleotide polymorphisms studied in the GABRA4, GABRE, and GABRQ genes are not related to the risk for familial ET. PMID: 21422964
  7. truncated alpha 4 N-terminus may play a post-translational regulatory role in intracellular folding/glycosylation/assembly of the alpha 4 subunit PMID: 12242096
  8. GABRA4 is involved in the etiology of autism and potentially increases autism risk through interaction with GABRB1. PMID: 16080114
  9. These results confirmed our earlier findings, indicating GABRA4 and GABRB1 as genes contributing to autism susceptibility, extending the effect to multiple ethnic groups and suggesting seizures as a stratifying phenotype. PMID: 16770606
  10. alpha4beta3gamma2L receptors have unique kinetic properties that limit the range of GABA applications to which they can respond maximally. PMID: 17124266
  11. Only two of the newly genotyped SNPs, rs10517173, rs16851647, were associated with nicotine dependence (observed P-values of 0.002, corrected FDR-BH P-values of 0.02). However, these SNPs were in complete LD with each other and with rs11731576. PMID: 19207358
  12. Lower delta mRNA levels in schizophrenia might reflect a reduced number of alpha(1)beta(x)delta GABA(A) receptors that could contribute to deficient tonic inhibition and prefrontal cortical dysfunction in schizophrenia. PMID: 19289452
