Fitm2 Gene Summary [Rat]
Predicted to enable coenzyme A diphosphatase activity; diacylglycerol binding activity; and triglyceride binding activity. Predicted to be involved in several processes, including fat cell differentiation; intracellular triglyceride homeostasis; and lipid droplet formation. Predicted to act upstream of or within triglyceride storage. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in Siddiqi syndrome. Orthologous to human FITM2 (fat storage inducing transmembrane protein 2). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Fitm2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
