Abstract

We have identified two additional members of the neuronal nicotinic acetylcholine receptor (nAChR)-related gene family. cDNA clones for one new gene, designated alpha 5, were isolated from rat hippocampus and rat PC12 cell line cDNA libraries. The alpha 5 gene encodes a protein of 48,800 daltons (424 amino acids) which exhibits significant overall amino acid sequence identity with the previously cloned rat nAChR subunits alpha 1 (49%), alpha 2 (55%), alpha 3 (52%), and alpha 4 (49%). Features characteristic of other nAChR alpha-subunits are present such as conserved cysteine residues at positions 127, 141, 191, and 192, and four strongly hydrophobic domains. A second addition to the nAChR-related gene family, designated beta 4, is encoded in overlapping rat genomic clones lambda DD15 and lambda RG518A. The beta 4 gene, encoding a mature protein of 53,300 daltons (475 amino acids), consists of 6 exons and has a transcription unit length of approximately 18 kilobase pairs. The beta 4 gene encoded protein shows considerable amino acid sequence identity with nAChR beta 1 (43%), beta 2 (64%), and beta 3 (44%) subunits. Northern blots showed that, along with alpha 3 and beta 2, transcripts for both the alpha 5 and beta 4 genes are present in the PC12 cell line, while in situ hybridization experiments demonstrated expression of the alpha 5 and beta 4 genes in a small number of nuclei in the central nervous system. Finally, the genes that encode the beta 4, alpha 3, and alpha 5 proteins are transcribed with convergent polarities and form a tightly linked gene cluster spanning approximately 60 kilobase pairs.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Mice heterozygous for the α3 subunit show attenuated nicotine-induced seizures, and α3 lies in the same gene cluster as α5 and β4.

    “Attenuation of nicotine-induced seizure is also present in mice heterozygous for the α3 subunit, which is found in the same gene cluster that contains α5 and β4 (Boulter et al. 1990, Salas et al. 2004a).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
