Diaph3 Gene Summary [Mouse]

Enables actin binding activity; microtubule binding activity; and protein homodimerization activity. Involved in actin filament polymerization. Acts upstream of or within several processes, including autophagosome-lysosome fusion; cytoskeleton organization; and myeloid cell differentiation. Located in cytoplasm and nucleus. Part of ESCRT I complex and filamentous actin. Is active in several cellular components, including cleavage furrow; cytoskeleton; and stereocilia tip-link density. Is expressed in several structures, including alimentary system; brain; gonad; submandibular gland primordium; and vibrissa. Used to study autosomal dominant auditory neuropathy 1 and congenital dyserythropoietic anemia. Human ortholog(s) of this gene implicated in autosomal dominant auditory neuropathy 1. Orthologous to human DIAPH3 (diaphanous related formin 3). [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 Diaph3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
