Abnormal T cell lineages. Leptoderan male tail. Phasmid dye fill defective (due to T cell lineage defect).

Although hermaphrodites appear WT in other ways, there are some problems with T cell lineages (affecting the phasmids) and tail cell fusions. Variably Dyf. Male tail tip morphogenesis is also defective, resulting in blobby, "leptoderan" tails. Males are infertile due to an inability to properly copulate. tlp-1 encodes a nuclear protein with a single C2H2-type zinc finger domain and an N-terminal "SPLALLA" domain, similar to that of Sp1 transcription factors of vertebrates. The bx85 mutation involves a truncation of TLP-1 due to a frameshift caused by a 5-bp deletion.

Unc. Although hermaphrodites appear WT in other ways, there are some problems with T cell lineages (affecting the phasmids) and tail cell fusions. Variably Dyf. Male tail tip morphogenesis is also defective, resulting in blobby, "leptoderan" tails. Males are infertile due to an inability to properly copulate.

Deficiency covers at least all of cosmid T23G4; right breakpoint may be in cosmid C47A4. Fails to complement tlp-1(bx85). Viable and fertile. Although hermaphrodites appear WT in other ways, there are some problems with T cell lineages (affecting the phasmids) and tail cell fusions. Variably Dyf. Male tail tip morphogenesis is also defective, resulting in blobby, "leptoderan" tails. Males are infertile due to an inability to properly copulate.
