Predicted to enable several functions, including 2-iminobutanoate deaminase activity; endoribonuclease activity, producing 3'-phosphomonoesters; and identical protein binding activity. Predicted to be involved in negative regulation of epithelial cell proliferation; negative regulation of gene expression; and organonitrogen compound catabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and lung. Orthologous to human RIDA (reactive intermediate imine deaminase A homolog). [provided by Alliance of Genome Resources, Apr 2022]
