Btd Gene Summary [Mouse]
Enables biotinidase activity. Involved in biotin metabolic process. Located in apical part of cell; nucleolus; and perikaryon. Is active in extracellular region. Is expressed in blood vessel; inner ear; nervous system; and urinary system. Used to study biotinidase deficiency. Human ortholog(s) of this gene implicated in biotinidase deficiency. Orthologous to human BTD (biotinidase). [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 Btd often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- Vanin C-terminal domain
- nitrilase
- biotinidase
