Ddhd2 Gene Summary [Rat]

Predicted to enable phospholipase activity and triacylglycerol lipase activity. Predicted to act upstream of or within lipid droplet organization; positive regulation of mitochondrial fission; and triglyceride catabolic process. Predicted to be located in centriolar satellite and cytosol. Predicted to be active in COPII-coated ER to Golgi transport vesicle and membrane. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 54. Orthologous to human DDHD2 (DDHD domain containing 2). [provided by Alliance of Genome Resources, Jul 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 Ddhd2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
