WormBase Gene ID  ? WBGene00003968 Gene Name  peb-1
Sequence Name  ? T14F9.4 Brief Description  peb-1 encodes a novel DNA-binding protein; during development, peb-1 activity is required for proper morphogenesis of the pharynx, vulva, and hindgut and for normal molting, feeding, and body morphology; in vitro, PEB-1 exhibits sequence-specific DNA binding to a regulatory sequence known as subelement C, which directs pharynx-specific myo-2 expression and in yeast, PEB-1 exhibits modest transcription activation activity; PEB-1 is expressed in the nuclei of all pharyngeal cells (except neurons) from the comma stage of embryogenesis through late larval stages; in addition, PEB-1 is expressed dynamically in non-pharyngeal cells, including the vulva, germline, hindgut, and hypodermis.
Organism  Caenorhabditis elegans Automated Description  Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Located in nucleus. Expressed in several structures, including germ line; hypodermis; pharyngeal cell; pharyngeal-intestinal valve; and rectal epithelial cell.

See Expr837, 839, 840 for Expr_pattern of the same locus.   Expr838 In embryos, PEB-1 protein was strongly detected in the nuclei of many cells in the developing pharynx. Staining was first detected at the comma stage. Some pharyngeal cells do not express PEB-1, observed a cluster of nuclei that do not contain PEB-1 near the center of the developing pharynx, a region containing many of the pharyngeal neurons. Strong pharyngeal staining persisted through the remainder of embryogenesis. PEB-1 staining was also observed outside the pharynx in several cells near the rectum and in the tail and at lower level in hypodermal nuclei. In early larvae, PEB-1 protein is easily detectable in the pharynx, as well as in a subset of nonpharyngeal. Consistently observed PEB-1 protein in the nuclei of all pharyngeal muscles, marginal cells, epithelial cells, gland cells, and pharyngeal-intestinal valve cells. Notably, authors did not observe PEB-1 staining in any pharyngeal neurons. Pharyngeal PEB-1 staining decreased in late larvae until it became undetectable in adults. PEB-1 protein expression was also observed in some tissues outside the pharynx in larvae and adults. In general, the nonpharyngeal expression was weaker than expression in the pharynx, and it appeared dynamic during the worm life cycle. In larvae, PEB-1 antibody staining was reproducibly observed in several cells near the rectum and in hypodermal nuclei in the tail and in the developing vulva and surrounding cells. Authors also observed protein expression in several nuclei in the head and tail that were provisionally identified as hypodermal nuclei. In older larvae and adults, the rectal and vulval expression decreased, but PEB-1 staining was visible in germ-line cells. This expression is consistent with Northern blots indicating that peb-1 mRNA is expressed in the germ line. PEB-1 protein was strongly detected in the nuclei.
Reporter gene fusion type not specified. See Expr837, 838, 840 for Expr_pattern of the same locus.   Expr839 Very strong beta-galactosidase expression in the pharynx from the comma stage of embryogenesis through late larval stages, and frequent expression was observed in muscle cells and marginal cells, while less frequent expression was observed in epithelial cells and the pharyngeal intestinal valve cells. Reporter expression was also observed outside the pharynx in a pattern similar to that of the endogenous PEB-1 protein.  
Reporter gene fusion type not specified.   Expr3374 Expressed in both sexes pharynx; male tail; herm vulva.  
    Expr3389 Expressed in pharynx and gonad (L2 to Adult).  
    Expr1200173 Data from the TransgeneOme project  
    Expr12258 Like endogenous PEB-1, GFP::PEB-1 was expressed in the pharynx and hypodermis beginning at the comma stage of embryogenesis and was tightly localized to nuclei throughout development. Expression was also observed in the gut, and in some cases body wall muscle and seam cells, where PEB-1 antibody staining was not reproducibly detected.  
See Expr837, 838, 839 for Expr_pattern of the same locus.   Expr840 peb-1 mRNA accumulation in the pharynx. Did not observe localized peb-1 mRNA accumulation outside the pharynx.  
    Expr1800 Expressed in pharynx.  
Interestingly, Y is replaced in the hindgut by P12.pa, a descendant of the only P cell in which PEB-1 protein expression was detected in L1 larvae. No detailed description on cellular expression patterns in pharynx, try to find those information in Expr838.   Expr3462 In summary, PEB-1 accumulated in L1 larvae in the nuclei of all hypodermal cells and the epithelial cells lining the rectal lumen. As in the pharynx, PEB-1 was not detectable in neuroblasts or differentiated neurons. PEB-1-expressing cells are not obviously related by cell type or lineage. Rather, one striking common feature of these cells is that they contact the cuticle on the exterior of the worm or lining the pharyngeal or rectal lumen. Like in the pharynx, PEB-1 was first detected in the hypodermal nuclei in comma stage embryos (approximately 400 min) and remained detectable until hatching. In 1 1/2-fold stage embryos, the PEB-1 protein was detected in the nuclei of most, if not all, hypodermal cells including hyp5, hyp6, and hyp7 and the H, P, and V cells. After hatching, PEB-1 remained detectable in most hypodermal cells although it decreased in later larvae and was undetectable in adults. In the L1 lateral hypodermis, the PEB-1 protein was detected in H0, H1, H2, V1 to V6, and T, and their anterior and posterior daughters, as well as in the nuclei of the hyp7 syncytium. PEB-1 was also detected in many of the dorsal and ventral hypodermal nuclei in the head and the ventral hypodermal nuclei in the tail. Notably, PEB-1 was not detected in larval P cells. In addition, PEB-1 was not detected in other neuroblasts including Q and T.p. PEB-1 was also expressed in cells lining the lumen of the hindgut. In 1 1/2-fold embryos (approximately 420 min), PEB-1 was detected in many nuclei near the posterior of the embryo. These likely include both the posterior hypodermal cells and hindgut cells, although these cells cannot be easily distinguished at this stage. In L1 larvae, PEB-1 was detected in many of the non-neuronal nuclei surrounding the rectal lumen, including K, K', U, F, B, and Y. PEB-1 was not detected in the rectal-intestinal valve or the anal depressor muscle. As in other tissues, the PEB-1 protein remained detectable in the hindgut throughout larval development but became progressively less abundant and undetectable in adults. Importantly, this progressive decrease in PEB-1 expression also occurs in Y, which withdraws from the hypodermis during late larval development to become a neuron. nuclei
