Predicted to enable protein homodimerization activity. Predicted to be involved in several processes, including negative regulation of cold-induced thermogenesis; negative regulation of tumor necrosis factor production; and positive regulation of sequestering of triglyceride. Predicted to act upstream of or within lipid metabolic process and response to stilbenoid. Predicted to be located in mitochondrial envelope and nucleus. Predicted to colocalize with lipid droplet. Human ortholog(s) of this gene implicated in obesity. Orthologous to human CIDEA (cell death inducing DFFA like effector a). [provided by Alliance of Genome Resources, Apr 2022]
