    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 功能：
    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 permeable to sodiun ions.

    1. MAFA controls autonomic nervous system-mediated insulin secretion by activating the transcription of nicotinic (ChrnB2 and ChrnB4) receptor genes, which is impaired in patients with type 2 diabetes. PMID: 26904947
    2. Data show efficient expression of (alpha6beta2)2beta3 nicotinic acetylcholine receptors (AChRs) in Xenopus oocytes using free subunits with only small changes in alpha6 subunits, while not altering AChR pharmacology or channel structure. PMID: 25068303
    3. The results of this study suggested that rs2072660 had a significant effect on the nicotine dependence There was no direct association between depressive phenotype (with neither ZSDS total scores and nor its subscales) and CHRNB2 variants. PMID: 25640319
    4. Following smoking reduction and cessation alpha4beta2* nAChR densities were decreased across brain regions. PMID: 23429692
    5. Evidence for significant association between common sequence variants in CHRNB2 and nausea severity was obtained after adjusting for age, gender and correlated tests in patients using varenicline for smoking cessation. PMID: 21606948
    6. A novel mutant mouse harboring the human ADNFLE mutation in the Chrnb2 gene was generated and used to study the roles of beta2* nicotinic receptors in complex biological processes including the activity-rest cycle, natural reward and anxiety. PMID: 20603624
    7. variation in the promoter region of CHRNB2 gene may be important in mediating levels of expression of the beta2 nicotinic receptor subunit, which may be associated with variation in subjective response to nicotine PMID: 20854418
    8. mutations of CHRNB2 and CHRNA2 genes may be rare in Chinese autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) PMID: 21287502
    9. Concatameric pentamers and pentamers formed from combinations of trimers, dimers, and monomers of alpha6beta2beta3* acetylcholine receptors exhibit similar properties, indicating that the linkers between subunits do not alter their functional properties. PMID: 20923852
    10. The high sensitivity to activation and desensitization of (alpha4beta2)alpha5 nAChRbeta2 by nicotine results in a narrow concentration range in which activation and desensitization curves overlap. PMID: 20881005
    11. Using high-resolution NMR spectroscopy, we solved the structure of the entire transmembrane domain (TM1234) of the beta2 subunit. We found that TM1234 formed a four-helix bundle in the absence of the extracellular and intracellular domains. PMID: 20441771
    12. Data suggests that beta(2)*-nAChRs play a role in pain sensitivity but not pain tolerance during tobacco smoking withdrawal. PMID: 20371741
    13. There was no evidence of association of any of the SNPs in CHRNAB2 (rs2072661, rs4845378) or CHRNAB3 (rs4953, rs6474413) with smoking status (p=0.30) or, among daily smokers, of association with cotinine levels (p=0.08). PMID: 19482438

    19. Mutations in genes coding for the alpha 4 and beta 2 subunits of the neuronal nicotinic acetylcholine receptor receptor (CHRN) are known to cause autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). PMID: 12681012

    22. Here, we report a new CHRNB2 mutation located in transmembrane region 3 (M3), outside the known ADNFLE mutation cluster. The CHRNB2 mutation I312M, which occurred de novo in twins, markedly increases the receptor's sensitivity to acetylcholine. PMID: 15964197
    23. Greater beta2*-nAChR availability during early abstinence may impact the ability of smokers to maintain abstinence. PMID: 16928859
    24. This study provides the first evidence for association between the CHRNB2 gene and nicotine- and alcohol-related phenotypes, and suggests that polymorphisms in CHRNB2 may be important in mediating early responses to nicotine and alcohol. PMID: 17226798
    25. To our knowledge, this is the third family reported presenting a mutation in CHRNB2 in nocturnal frontal lobe epilepsy. PMID: 17900292
