Predicted to enable endoribonuclease activity. Predicted to be involved in RNA catabolic process. Predicted to be located in endoplasmic reticulum lumen; extracellular space; and lysosome. Predicted to be active in extracellular region. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in RNASET2-deficient cystic leukoencephalopathy. Orthologous to human RNASET2 (ribonuclease T2). [provided by Alliance of Genome Resources, Apr 2022]
