Becn1 Gene Summary [Mouse]
Enables identical protein binding activity and protein-macromolecule adaptor activity. Involved in autophagosome assembly; cellular response to glucose starvation; and engulfment of apoptotic cell. Acts upstream of or within several processes, including amyloid-beta metabolic process; negative regulation of autophagosome assembly; and positive regulation of cardiac muscle hypertrophy. Located in autophagosome; phagocytic vesicle; and trans-Golgi network. Part of phosphatidylinositol 3-kinase complex, class III. Is active in cytoplasm. Is expressed in several structures, including brain; extraembryonic visceral endoderm; jaw; oral epithelium; and sensory organ. Used to study systemic lupus erythematosus. Human ortholog(s) of this gene implicated in Machado-Joseph disease and breast cancer. Orthologous to human BECN1 (beclin 1). [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 mouse Becn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
