WormBase Gene ID  ? WBGene00000042 Gene Name  acr-2
Sequence Name  ? K11G12.2 Brief Description  A homolog of a non-alpha type nicotinic acetylcholine receptor subunit that forms a functional channel when co-expressed with the unc-38 alpha subunit.
Organism  Caenorhabditis elegans Automated Description  Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in several processes, including calcium ion import across plasma membrane; neuromuscular synaptic transmission; and positive regulation of translation. Located in neuron projection. Expressed in AVE; DVB; cholinergic neurons; somatic nervous system; and vulval muscle. Human ortholog(s) of this gene implicated in lung disease (multiple); nicotine dependence; and stomach cancer. Is an ortholog of human CHRNA3 (cholinergic receptor nicotinic alpha 3 subunit) and CHRNA6 (cholinergic receptor nicotinic alpha 6 subunit).

  Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells. DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction. WBPaper00060811:L1_vs_adult_upregulated_neural
  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
  Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage. A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

    Expr10808 ACR-2::GFP showed mostly diffused localization on neuronal soma, as well as processes in the ventral cord, sublateral cords, and nerve ring. In the ventral cord, expression of ACR-2::GFP was specifically observed in the VA, VB, DA, and DB motor neurons as reported previously (Jospin et al., 2009). Several additional cells (e.g., SDQ, vulva muscles) also expressed ACR-2::GFP, presumably because of the use of a longer promoter and inclusion of intronic sequences. However, staining of ACR-2::GFP was not seen in the dorsal nerve cord. Because the axonal processes of DA and DB motor neurons are major constituents of the dorsal nerve cord, lack of ACR-2::GFP signals in the dorsal nerve cord indicates that ACR-2 is unlikely to localize to presynaptic sites of these motor neurons.  
    Expr15314    
Picture: Figure 3A, 3B.   Expr8872 Both promoters drove expression predominantly in the neurons of the ventral cord from L1 larvae to adults. These neurons were determined to be cholinergic motor neurons of the VA, VB, DA, and DB classes, and not the AS and VC classes. GFP expression driven by the longer acr-2 promoter was frequently seen in the PVQ and DVC neurons in the tail and was infrequently observed in a few head neurons. Coexpression with reporter genes for GABAergic neurons and interneurons confirmed that the acr-2 transcriptional reporters were not expressed in the ventral cord GABAergic motor neurons or in the interneurons expressing glr-1 or nmr-1.  
Picture: Fig. 1 A.   Expr9149 Expression of Pacr-2::GFP was limited to the nervous system and largely restricted to neurons located in the ventral nerve cord. Expression of Pacr-2::GFP did not overlap with expression of a GABAergic mCherry reporter (Punc-47::mCherry), indicating that expression of acr-2 was limited to cholinergic motor neurons (DA, VA, DB, VB) in the ventral nerve cord of adult animals.  
Picture: Fig S1.   Expr9150 Expression of the GFP reporter construct could be observed at all larval stages and in the adult. The onset of expression was seen in late embryogenesis by the threefold stage (~550 min after fertilization). ACR-2 is diffusely localized with enriched expression in the dendritic compartment of cholinergic motor neurons. In first larval stage (L1) animals, when DA and DB motor neurons are the sole excitatory motor neurons present, ACR-2 expression was clearly visible in ventral nerve cord processes. In adult animals, the fusion protein was diffusely localized to neuronal processes of the dorsal and ventral nerve cords.

ACR-2::GFP signal was observed at DA9 soma, its entire dendritic branch, and the ventralmost proximal axonal region immediately posterior to soma. ACR-2::GFP staining was not detectable in the commissure or any part of the dorsal branch. Moreover, the dendritic ACR-2::GFP in DA9 did not show prominent clustering.
