Predicted to enable SMAD binding activity; identical protein binding activity; and ubiquitin protein ligase activity. Predicted to be involved in several processes, including negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway; positive regulation of trophoblast cell migration; and ubiquitin-dependent protein catabolic process. Predicted to be located in nuclear speck. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm. Is expressed in cardiovascular system; eye; genitourinary system; gut; and lung. Used to study diffuse large B-cell lymphoma. Orthologous to human SMURF2 (SMAD specific E3 ubiquitin protein ligase 2). [provided by Alliance of Genome Resources, Apr 2022]
