WormMine: Gene WBGene00006649

• WormBase Gene ID: WBGene00006649
• Gene Name: tth-1
• Sequence Name: F08F1.8
• Brief Description: tth-1 encodes a thymosin beta ortholog that contains four functionally distinct thymosin beta repeats; in vitro, TTH-1 binds multiple actin monomers as well as filamentous actin suggesting that, as its homology predicts, TTH-1 plays a direct role in regulating actin polymerization and cytoskeletal organization in C. elegans; consistent with this, loss of tth-1 activity via a deletion mutation that removes upstream sequences results in animals with a dumpy morphology that are sterile as a result of maternal effect lethality associated with deformed oocytes containing abnormally distributed actin; tth-1 mRNA is present throughout development, while TTH-1 protein is detected in the adult gonad in the inside edges of the membranous structures surrounding germline nuclei, the cytoplasm and cortex of oocytes, early embryos at points of cell contact, the developing nerve ring, and then throughout the larval and adult body, with specific enrichment in the intestine and spermatheca.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable actin monomer binding activity. Predicted to be involved in actin filament organization. Predicted to be located in cytosol. Expressed in distal tip cell; nerve ring; oocyte; spermatheca; and terminal bulb.
• Biotype: SO:0001217
• Genetic Position: X :-0.047642 ±0.01533

8 Expression Patterns

• Primary Identifier: Expr2035703
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Primary Identifier: Expr12265
• Pattern: The localization of tetraThymosin-beta is shown in oocytes (in dissected gonads of adult worms), in embryos and in whole adult organisms. TetraThymosin-beta was maternally expressed and in the adult gonad diffusely present in the cytoplasm of the oocytes, with strong staining at the cell cortex where also actin is present. In the distal arm of the gonad, tetraThymosin-beta localized to the inside edges of the membrane cubicles surrounding germ cell nuclei. Here, tetraThymosin-beta did not localize to the lateral side of the membrane cubicles where actin is arranged in a 'honeycomb' structure (Strome, 1986). In two-cell stage embryos, tetraThymosin-beta was enriched in the cell-cell contact where actin was also concentrated. The tetraThymosin-beta signal was clearly apparent until the four-cell stage and became weaker later on. At the comma stage (290 min after the first cell division), tetraThymosin-beta staining was observed at the developing nerve ring that is the largest axonal bundle in the nematode body and that positions around the isthmus of the pharynx. TetraThymosin-beta was evident in this region even before a clear actin signal was apparent. In larvae and adults, immunofluorescence yielded a diffuse but specific staining of the entire worm body with enrichment at the intestinal tract and spermatheca. At these stages, in contrast to what is observed in developing embryo, no prominent signal was observed in the head region where the nerve ring is located. In young adults is expressed in theposterior bulb of the pharynx. These immunostaining patterns were reproducible in three or more experiments and in 20 or more worms or embryos.
