Enriched in several structures, including anterior arcade cell; interneuron; nerve ring neurons; pharynx; and ventral nerve cord based on microarray; tiling array; RNA-seq; and single-cell 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 twenty chemicals including methylmercury hydroxide; Zidovudine; and allantoin based on RNA-seq and microarray studies. Human MBLAC1 enables RNA endonuclease activity and metal ion binding activity. Is predicted to encode a protein with the following domains: Metallo-beta-lactamase; Ribonuclease Z/Hydroxyacylglutathione hydrolase-like; and Metallo-beta-lactamase domain-containing protein 1. Is an ortholog of human MBLAC1 (metallo-beta-lactamase domain containing 1).
