Enriched in head mesodermal cell; intestine; mechanosensory neurons; rectal epithelial cell; and terminal bulb based on microarray; tiling array; RNA-seq; and single-cell RNA-seq studies. Is affected by several genes including daf-16; skn-1; and hsf-1 based on microarray; tiling array; proteomic; and RNA-seq studies. Is affected by four chemicals including Chlorpyrifos; Diazinon; and Humic Substances based on microarray studies. Is predicted to encode a protein with the following domains: Ankyrin repeats (3 copies); Ankyrin repeat; Beta-hexosaminidase-like, domain 2; Ankyrin repeat-containing domain superfamily; and Phosphorylation site.
