Predicted to act upstream of or within in utero embryonic development; olfactory behavior; and suckling behavior. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm. Orthologous to human UBR3 (ubiquitin protein ligase E3 component n-recognin 3). [provided by Alliance of Genome Resources, Apr 2022]
