Predicted to enable CoA pyrophosphatase activity; diacylglycerol binding activity; and triglyceride binding activity. Predicted to be involved in several processes, including cellular triglyceride homeostasis; lipid droplet formation; and positive regulation of sequestering of triglyceride. Predicted to act upstream of or within sequestering of triglyceride. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of endoplasmic reticulum membrane. Orthologous to human FITM2 (fat storage inducing transmembrane protein 2). [provided by Alliance of Genome Resources, Apr 2022]
