Flnb Gene Summary [Mouse]
Predicted to enable identical protein binding activity. Acts upstream of or within several processes, including cellular response to type II interferon; epithelial cell development; and skeletal muscle tissue development. Located in several cellular components, including brush border; focal adhesion; and stress fiber. Is expressed in several structures, including alimentary system; brain; facial prominence; sensory organ; and skeleton. Used to study spondylocarpotarsal synostosis syndrome. Human ortholog(s) of this gene implicated in Larsen syndrome; bone development disease (multiple); cleft palate; and spinal disease (multiple). Orthologous to human FLNB (filamin B).

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 Flnb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
