Expression Pattern :

Pattern  NLP-22 is selectively expressed, in a single-neuron pair, the RIAs. NLP-22 is predicted to be secreted. When GFP was fused to the C-terminus of the NLP-22 preproprotein, green fluorescence was observed in several neurons in the head as well as in the ventral nerve cord, supporting the notion that NLP-22 is a secreted peptide. mRNA abundance of the gene nlp-22 was higher in the L4 stage than in lethargus. Using qRT-PCR, we confirmed that nlp-22 mRNA expression cycles with a constant phase relationship to lethargus. nlp-22 mRNA peaked midway through the active larval stages, decreased during each lethargus stage, and was absent in adults. Primary Identifier  Expr11400
Reporter Gene  [pnlp-22::GFP] transcriptional fusion and [Pnlp-22::nlp-22:gfp; Pmyo-2::mCherry; unc-119(+)] translational fusion. The transcriptional reporter for nlp-22 (Pnlp-22:Intron:gfp) was made by fusing the promoter of nlp-22 (-450 to +3) to the coding sequence of GFP, amplified from pPD95.75 and replacing one of the synthetic introns of gfp with the intron of nlp-22( +85 to +481).
