Enables ribonucleoprotein complex binding activity. Acts upstream of or within fat cell differentiation; positive regulation of glucose import; and regulation of mRNA stability. Predicted to be located in nuclear matrix. Is expressed in cerebellum; embryo; hippocampus; retina inner nuclear layer; and retina outer nuclear layer. Human ortholog(s) of this gene implicated in Lynch syndrome and prostate cancer. Orthologous to human RNASEL (ribonuclease L). [provided by Alliance of Genome Resources, Apr 2022]
