Enriched in hypodermis and intestine based on tiling array and RNA-seq studies. Is affected by several genes including daf-16; daf-2; and skn-1 based on microarray and RNA-seq studies. Is affected by five chemicals including hydrogen sulfide; sodium arsenite; and paraquat based on microarray; RNA-seq; and proteomic studies. Is predicted to encode a protein with the following domains: Regulator of chromosome condensation, RCC1; Regulator of chromosome condensation (RCC1) repeat; and Regulator of chromosome condensation 1/beta-lactamase-inhibitor protein II. Is an ortholog of human RCCD1 (RCC1 domain containing 1).
