WormBase Gene ID  ? WBGene00007750 Gene Name  syg-2
Sequence Name  ? C26G2.1 Brief Description  syg-2 encodes a transmembrane protein that is a member of the immunoglobulin superfamily of proteins; during larval development, SYG-2 activity is required in vulval epithelial cells for proper synaptic specificity of the HSNL neuron; in regulating synapse formation, SYG-2 acts as a guidepost protein for the SYG-1 receptor that interacts with SYG-2 and acts within HSNL to regulate synaptic specificity; a SYG-2::GFP fusion protein is expressed in the primary vulval cell lineages beginning at the L3 larval stage, with expression increasing during the L4 stage and finally disappearing by adulthood; in embryos, SYG-2::GFP expression is detected in some head neurons and body wall muscles, the latter of which also express the reporter during the L1 and L2 larval stages.
Organism  Caenorhabditis elegans Automated Description  Enables cell adhesion molecule binding activity and protein homodimerization activity. Involved in cell-cell signaling; nervous system development; and protein localization to synapse. Predicted to be located in cell-cell junction and plasma membrane. Expressed in several structures, including P6.paa; P6.pap; P6.ppa; egg-laying apparatus; and neurons. Used to study nephrotic syndrome. Human ortholog(s) of this gene implicated in nephrotic syndrome type 1. Is an ortholog of human NPHS1 (NPHS1 adhesion molecule, nephrin).

  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.

Reference: personal communication from Oliver Hobert 2002-12-07.   Expr1766 Non-neuronal expression in: dorsal & ventral hypodermis  
    Expr3409 In the vulval region, SYG-2::GFP was expressed in epithelial cells of the primary lineage (P6.p descendents) beginning at the mid to late L3 stage. The expression of SYG-2::GFP in the primary vulval epithelial cells increased as animals enter L4 stage, then disappeared within the first 6 hr of adulthood. This expression pattern matched the expression of syg-2 mRNA observed by in situ hybridization. During embryogenesis, SYG-2::GFP is expressed in a subset of neurons in the head and in body wall muscles. In the L1 and L2 larval stages, when many motor neuron synapses develop, SYG-2::GFP is expressed in head and body wall muscles and in punctate structures near the ventral nerve cord that may correspond to body wall muscle arms.
