WormBase Gene ID  ? WBGene00003996 Gene Name  pgp-2
Sequence Name  ? C34G6.4 Brief Description  pgp-2 encodes a member of the ABC transporter family with highest similarity to the vertebrate MDR (multidrug resistance) family and that is orthologous to human MDR1 (ABCB1; OMIM:171050, mutated in Crohn disease); during development, pgp-2 activity is required, in parallel with that of the AP-3 adaptor complex, for the proper formation of gut granules, lysosome-related organelles found in the C. elegans intestine; pgp-2 is expressed in the intestine, from the E2 stage of embryonic development through adulthood; PGP-2 localizes to the gut granule membrane.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable ATPase-coupled transmembrane transporter activity. Involved in gut granule assembly and lipid storage. Located in gut granule membrane. Expressed in AWAL and AWAR. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); carcinoma (multiple); and intrahepatic cholestasis (multiple). Is an ortholog of human ABCB1 (ATP binding cassette subfamily B member 1); ABCB11 (ATP binding cassette subfamily B member 11); and ABCB4 (ATP binding cassette subfamily B member 4).

  Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 hours at 24 centigrade). For model 2, authors used 100 permutations to estimate the FDR threshold.

  Expression Pattern Group C, enriched for genes involved in metabolic processes. The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05. WBPaper00036286:Pattern_C

14 Expression Patterns

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
    Expr4687 Embryonic expression of pgp-2::gfp was first seen in the daughters of the E blastomere (E2 stage), which generate the intestine. Intestinal expression persisted through embryogenesis and into adulthood. Rarely, weak expression of pgp-2::gfp was detected in embryonic and adult hypodermal cells. Pharyngeal or AWA expression of the pgp-2::gfp reporter were never detected.  
    Expr4688   Intestinally expressed PGP-2::GFP was localized to prominent vesicular structures and the plasma membrane in embryos and adults. Similar organelles were stained by anti-PGP-2 antibodies. Anti-PGP-2 antibodies only stained intracellular compartments in embryos and adults, suggesting that the PGP-2::GFP might be partially mislocalized to the plasma membrane. PGP-2::GFP colocalized with birefringent material and the V-ATPase subunit FUS-1 in embryos, and in adults PGP-2::GFP colocalized with autofluorescent compartments. PGP-2 antibodies stained compartments containing GLO-1::GFP. These results indicate that PGP-2 and PGP-2::GFP are associated with the gut granule membrane.
Reporter gene fusion type not specified.   Expr4575 To identify the expression sites of the ABC transporter PGP-2, five independent reporter gene expressing strains carrying a pgp-2::GFP fusion construct were generated and analysed. In all cases, PGP-2-GFP was found in the AWA sensory neuron pair. This conclusion was validated by analysing the morphology of the cilia. The PGP-2 expressing neurons showed the characteristic branched cilium morphology typical of the AWA neurons.

    Expr10410 Inferred expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo.
