Flna Gene Summary [Rat]
Enables SMAD binding activity. Involved in several processes, including brain development; establishment of Sertoli cell barrier; and mRNA transcription by RNA polymerase II. Located in several cellular components, including cytoskeleton; dendrite; and neuronal cell body. Is active in glutamatergic synapse and postsynapse. Used to study periventricular nodular heterotopia. Human ortholog(s) of this gene implicated in X-linked chronic idiopathic intestinal pseudo-obstruction; bone development disease (multiple); heart valve disease (multiple); periventricular nodular heterotopia; and terminal osseous dysplasia. Orthologous to human FLNA (filamin A). [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 rat Flna often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
