What's a GeneRIF?

Beta3 nicotinic subunits do not seem to influence nicotine reward but plays an important role in affective nicotine withdrawal signs.
Title: The β3 subunit of the nicotinic acetylcholine receptor is required for nicotine withdrawal-induced affective but not physical signs or nicotine reward in mice.
Data provide evidence that the protective genetic variant at rs6474413 identified in human genetic studies reduces gene expression and that decreased beta3 gene expression in mice reduces nicotine intake
Title: The β3 subunit of the nicotinic acetylcholine receptor: Modulation of gene expression and nicotine consumption.
Chimeric nicotinic acetylcholine receptors reveal the roles for N-terminal extracellular domains of (nAChR) beta3 subunits in the receptor activity and function.
Title: Roles for N-terminal extracellular domains of nicotinic acetylcholine receptor (nAChR) β3 subunits in enhanced functional expression of mouse α6β2β3- and α6β4β3-nAChRs.
beta3 subunit coexpression promotes function of alpha6*-nAChR
Title: Modulation of gain-of-function α6*-nicotinic acetylcholine receptor by β3 subunits.
Data show that in Prkce(-/-) mice, conditioned place preference and self-administer behaviors are associated with reduced levels of alpha(6) and beta(3) nicotinic receptor subunit mRNA in the ventral midbrain and striatum.
Title: Protein kinase C epsilon modulates nicotine consumption and dopamine reward signals in the nucleus accumbens.
beta3-containing nicotinic receptors influence anxiety and may be critical for the continuation of smoking behaviors
Title: Decreased anxiety-like behavior in beta3 nicotinic receptor subunit knockout mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
