Tspo Gene Summary [Rat]
Enables androgen binding activity and benzodiazepine receptor activity. Involved in several processes, including positive regulation of programmed cell death; regulation of biosynthetic process; and regulation of glial cell proliferation. Located in mitochondrial outer membrane. Used to study cholesterol ester storage disease. Orthologous to human TSPO (translocator protein). [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 Tspo often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
