Enriched in NSM; intestine; and pharyngeal muscle cell based on tiling array; RNA-seq; proteomic; and single-cell RNA-seq studies. Is affected by several genes including daf-16; daf-2; and skn-1 based on microarray; tiling array; and RNA-seq studies. Is affected by twenty-five chemicals including methylmercuric chloride; rotenone; and Tunicamycin based on microarray and RNA-seq studies. Is predicted to encode a protein with the following domains: Domain of unknown function DUF4139; N-terminal domain of unknown function (DUF4140); Domain of unknown function (DUF4139); Domain of unknown function DUF4140; and Conserved hypothetical protein CHP02231.
