Enriched in several structures, including ABarpaapap; ABarpaappa; ABarpaappp; ABarppaapa; and anterior hypodermis based on tiling array and single-cell RNA-seq studies. Is affected by several genes including cyc-1; swsn-1; and etr-1 based on microarray; tiling array; and RNA-seq studies. Is affected by twenty-three chemicals including 1-methylnicotinamide; methylmercuric chloride; and mianserin based on RNA-seq and microarray studies. Is predicted to encode a protein with the following domains: Zona pellucida-like domain; Zona pellucida domain; and Cuticlin domain-containing protein.
