Rbm20 Gene Summary [Mouse]
Enables pre-mRNA intronic binding activity. Involved in heart formation; regulation of RNA splicing; and spliceosome-depend formation of circular RNA. Located in cytoplasmic ribonucleoprotein granule. Is active in nucleus. Is expressed in several structures, including diaphragm; extraembryonic component; heart; limb segment; and skeletal musculature. Used to study atrial fibrillation and dilated cardiomyopathy 1DD. Human ortholog(s) of this gene implicated in dilated cardiomyopathy and dilated cardiomyopathy 1DD. Orthologous to human RBM20 (RNA binding motif protein 20).

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 Rbm20 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
