Predicted to enable ubiquitin-like ligase-substrate adaptor activity. Involved in protein ubiquitination and ubiquitin-dependent protein catabolic process. Acts upstream of or within cellular response to prostaglandin stimulus; cellular response to xenobiotic stimulus; and larval feeding behavior. Predicted to be located in inclusion body. Predicted to be part of Cul3-RING ubiquitin ligase complex. Predicted to be active in cytoplasm. Is expressed in several structures, including gill; head; heart; liver; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in gallbladder cancer. Orthologous to human KEAP1 (kelch like ECH associated protein 1).
