Ddhd2 Gene Summary [Mouse]
Enables triacylglycerol lipase activity. Involved in lipid droplet organization and triglyceride catabolic process. Acts upstream of or within positive regulation of mitochondrial fission. Located in membrane. Used to study hereditary spastic paraplegia 54. 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 mouse 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.
