WormBase Gene ID  ? WBGene00006540 Gene Name  tbg-1
Sequence Name  ? F58A4.8 Brief Description  tbg-1 encodes gamma-tubulin; in C. elegans, tbg-1 activity is essential and is required fornormal bipolar spindle assembly and function, as well as the fast phase of female pronuclearmigration following fertilization; while tbg-1 is required for proper organization and function of kinetochore and interpolar microtubules, it does not appear to be absolutely required for microtubule nucleation and growth; TBG-1 localizes to centrosomes in both interphase and mitotic cells, exhibiting a dynamic behavior during mitosis that differs between anterior and posterior centrosomes.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable GTP binding activity and microtubule nucleator activity. Predicted to be a structural constituent of cytoskeleton. Involved in several processes, including maintenance of centrosome location; microtubule cytoskeleton organization; and regulation of cell cycle. Located in centrosome and cytoplasm. Expressed in gonad. Human ortholog(s) of this gene implicated in complex cortical dysplasia with other brain malformations 4 and inclusion body myositis. Is an ortholog of human TUBG2 (tubulin gamma 2).

  Genes that showed expression levels higher than the corresponding reference sample (L2 all cell reference). 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.

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
Reporter gene fusion type not specified.   Expr4690 It was observed that the fusion gene expression continued from embryonic and post-embryonic stages. At embryonic stage, several cells were stained in post-gastrulating embryos whereas in postembryonic stages staining of cells was seen from L1 to young adults.  
    Expr4689 It was found that the amount of transcript of tbg-1 varies significantly in different stages during the development. In embryos the expression of the gene was high; it has extremely low level of gene expression during L1 larval stage, increased from L2 to L4 stages and showed the maximum expression in young adult stage. In gravid adult stage, the expression was more than that of embryos.

Picture: Fig. 7, Fig. 5, and Fig. S2.   Expr8293   Meiotic spindle assembly initiates at nuclear envelope breakdown, when a diffuse cloud of microtubules fills the volume of the perforated nucleus. These microtubules then organize into a much smaller assembly of dense microtubule bundles by the time the oocyte ovulates into the spermatheca. By the time the embryo exits the spermatheca and enters the uterus, a bipolar, metaphase-length spindle is present within a vesicle-free zone visible by differential interference contrast. Before NEBD, GFP::TBG-1 became progressively more concentrated on the nuclear envelope as oocyte maturation progressed. At nuclear envelope breakdown, GFP::TBG-1 fluorescence entered the nuclear region, forming a diffuse cloud that might indicate association with either microtubules or vesicles derived from the nuclear envelope. This large, diffuse area of gamma-tubulin enrichment did not contract in diameter nor increase in local intensity, as did the alpha-tubulin. By the time the embryo exited the spermatheca into the uterus, no discrete localization of GFP::TBG-1 was observed in the vesicle-free zone that contains the metaphase I spindle. GFP::MEI-1 was also distributed throughout the volume of the perforated nucleus immediately after nuclear envelope breakdown. GFP::MEI-1 differed from GFP::TBG-1 in that it became highly concentrated on chromosomes and spindle poles during spindle assembly and remained concentrated on these structures throughout meiosis.

gamma-tubulin = tbg-1   Expr1102   gamma-Tubulin was detected at the centrosomes of mitotic germ cells localized at the distal tip of the gonad. In meiotic cells arrested at the pachytene stage in the middle of the gonad, g-tubulin staining of the centrosomes was more difficult to visualize. In oocytes arrested in diakinesis of prophase I in the proximal gonad, only a diffuse cytoplasmic g-tubulin staining was detected and no centrosomes. Immunostaining of mature oocytes failed to reveal any g-tubulin at the poles of both meiosis I and meiosis II spindles. The spermatheca of the hermaphrodite gonad and identified spermatocytes undergoing meiotic division was examed. g-Tubulin staining was detected at the poles of the spindles as focused dots corresponding to the centrosomes. Mature sperm cells were also observed, showing a weak dot staining at the position expected for the centrioles.

No detailed description for cellular expression pattern. Probably expressed everywhere. --wjc.   Expr1645   After affinity purification, the antibodies stained centrosomes brightly. In newly fertilized embryos, gamma-tubulin antibodies did not stain the maternal meiotic spindle, which is barrel shaped and lacks centrioles and asters. Centrosome staining was seen first as 2 small dots near the sperm pronucleus at the posterior pole. This is consistent with recruitment of maternal gamma-tubulin by sperm-supplied centrioles. The small dots of gamma-tubulin grew into bright spheres as the male and female pronuclei migrated to meet in the posterior hemisphere of the embryo. In later-stage embryos, gamma-tubulin antibodies stained tiny centrosomes in interphase cells and larger centrosomes in mitotic cells. Anti-gamma-tubulin immunofluorescence signal from centrosomes was reduced below detection in embryos from hermaphrodites injected with dsRNA made from the gamma-tubulin gene, confirming the specificity of the antibodies.
    Expr13320 tbg-1 encodes gamma-tubulin, a ubiquitous and highly conserved component of centrosomes in eukaryotic cells (Strome et al, 2001). Using smFISH we determined the localization of tbg-1 transcripts (red). tbg-1 transcripts are detected within distinct foci throughout the cytoplasm during both the first (A) and second (B) mitosis. tbg-1 transcripts are not enriched at centrosomes or either blastomere. In contrast, GFP tagged TBG-1 proteins (green signal; arrowheads) localize at centrosomes, as previously shown (Strome et al, 2001). Shown are projections from selected focal planes. Bar=10μm.  
    Expr13934 In non-ciliated neurons TBG-1 γ-tubulin is diffusely localized throughout the neuron and is only slightly enriched, at the dendrite tip.  
    Expr3451   During anaphase, the centrosomal spheres of gamma-tubulin became hollow, and 2 dots of gamma-tubulin appeared within each ring. After anaphase, the gamma-tubulin rings disappeared, and the dots grew into the next pair of centrosomes. Thus, the dots represent the recruitment of gamma-tubulin by separated and perhaps duplicated centrioles within the expanding and disassembling mother centrosome. The behavior of the posterior centrosome differed from that of the anterior centrosome during anaphase B spindle elongation. As described previously, unlike the anterior pole, which remained relatively stationary, the posterior pole swung from side to side and moved toward the posterior end of the embryo. After the posterior migration had ceased, the gamma-tubulin ring at the posterior pole flattened laterally, decreased in brightness, and appeared to fragment, as if subject to forces directed toward the lateral cortex. In contrast, the gamma-tubulin ring at the anterior pole persisted longer and showed little flattening or fragmentation as it decreased in brightness. In subsequent rounds of mitosis, this pattern of centrosomal gamma-tubulin dynamics was repeated on a progressively smaller scale.
    Expr13935 WBTransgene00025665 Ciliated neurons and URX show a consistent enrichment of TBG-1 γ-tubulin at the base of the cilium, as has been reported before (Bobinnec et al., 2000).
