Description
Recombinant Human Acetylcholine receptor subunit alpha (CHRNA1) is a partial length protein expressed with an N-terminal 6xHis-tagged in the E.coli. Its expression region corresponds to 21-255aa (Extracellular Domain) of human CHRNA1 protein. It underwent validation via the LC-MS/MS analysis. Its purity reached up to 90% determined by SDS-PAGE. Under reducing conditions, a molecular weight band of around 32 kDa was visualized on the gel. This recombinant CHRNA1 protein is in stock now.
CHRNA1 is a component of acetylcholine receptors (AChRs) that are neurotransmitter receptors in the neuronal system. This protein plays a role in acetlycholine binding/channel gating. The ACh/AChR signaling is essential to normal the central nervous system (CNS) function. Alterations in this signaling lead to multiple neuropsychiatric disorders, including Myasthenic Syndrome, Congenital, 1B, Fast-Channel and Myasthenic Syndrome, Congenital, 1A, Slow-Channel.

Target Background

Function
After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
Gene References into Functions
  1. In our analysis, we found one pair of SNPs in CHRNA1 and CHRNA7, plus one pair of SNPs in CHRNA2 and CHRNA3 reached corrected significance in tests for GxG interaction. Our study suggested evidence of interactions between CHRNs in controlling the risk of NSCL/P. PMID: 29688589
  2. This study shown that the genetic analysis revealed that the very early onset JMG had a more prominent genetic predisposition in an autoantigen gene (CHRNA1). PMID: 28364296
  3. Data suggest that the mutations made the cholinergic receptor nicotinic alpha 1 subunit channel (CHRNA1) resistant to the antagonists, not by impairing antagonist binding, but rather by producing a gain-of-function phenotype, e.g. increased agonist sensitivity. PMID: 27649498
  4. Study indicated that nicotinic acetylcholine receptor alpha 1-subunit peptides may act as receptor decoy molecules and inhibit the binding of virus to the native host cell receptors and hence may reduce viral infection. PMID: 26656837
  5. ChRnA1 gene variants did not affect the pharmacodynamics of rocuronium. PMID: 25279974
  6. nicotine contributes to the progression and erlotinib-resistance of the NSCLC xenograft model via the cooperation between nAChR and EGFR. PMID: 25670150
  7. show that AON complementary to the 5' splice site of the exon was the most effective at exon skipping of the minigene with causative mutations, as well as endogenous wild-type CHRNA1 PMID: 25888793
  8. The CHRNA1 extracellular domain is an improved protein for use in antigen-specific Myasthenia Gravis therapeutic strategies. PMID: 24376846

  11. No mutations were found in CHRNG, CHRND and CHRNA1 genes of Indian families with Escobar syndrome. PMID: 23448903
  12. Findings identify a novel lung cancer risk locus on 2q31.1 which correlates with CHRNA1 expression and replicate previous associations on 15q25.1 in African-Americans. PMID: 23232035
  13. V188 is functionally linked to Y190 in the C-loop and to D200 in beta-strand 10 of the acetylcholine receptor alpha subunit, which connects to the M1 transmembrane domain PMID: 22728938
  14. Studies suggest that the receptor nAChRalpha1 is an important regulator of calpain-1 activation and inflammation in the chronic hypercholesterolemic nephropathy. PMID: 20661225

  16. DNA analysis of a father and son with dominant fast channel congenital myasthenic syndrome revealed an AChR alpha-subunit F256L missense mutation affecting channel gating PMID: 15079006
  17. A good correlation was found between the expression of PAX3/7-FKHR and AChR, while MyoD1 was more sensitive but less specific. PMID: 16435141
  18. the interaction between alpha AChR M1 and M2 domains plays a key role in channel gating PMID: 17028140
  19. growth factor-induced HMVEC migration, a key angiogenesis event, requires nAChR activation--an effect mediated in part by nAChR-dependent regulation of thioredoxin activity. PMID: 17082486
  20. Here we describe a mechanism controlling thymic transcription of a prototypic tissue-restricted human auto-antigen gene, CHRNA1 PMID: 17687331
  21. No CHRNA1, CHRNB1, or CHRND mutations were detected, but a homozygous RAPSN frameshift mutation, c.1177-1178delAA, was identified in a family with three children affected with lethal fetal akinesia sequence. PMID: 18179903
  22. study reports homozygous nonsense mutations in CHRNA1 and CHRND and shows that they were lethal PMID: 18252226
