Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process and protein polyubiquitination. Predicted to act upstream of or within several processes, including glycogen biosynthetic process; regulation of protein localization to plasma membrane; and regulation of protein modification process. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in Lafora disease. Orthologous to human NHLRC1 (NHL repeat containing E3 ubiquitin protein ligase 1). [provided by Alliance of Genome Resources, Apr 2022]
