Smarca4 Gene Summary [Mouse]

Enables several functions, including ATP hydrolysis activity; DNA polymerase binding activity; and lncRNA binding activity. Involved in nervous system development; positive regulation of Wnt signaling pathway; and positive regulation of metabolic process. Acts upstream of or within with a negative effect on gene expression. Acts upstream of or within several processes, including blastocyst development; circulatory system development; and erythrocyte differentiation. Located in euchromatin; male germ cell nucleus; and perichromatin fibrils. Part of SWI/SNF complex; nBAF complex; and npBAF complex. Is active in nucleus. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Used to study breast cancer. Human ortholog(s) of this gene implicated in Coffin-Siris syndrome 4; hepatocellular carcinoma; lung non-small cell carcinoma; and rhabdoid tumor predisposition syndrome 2. Orthologous to human SMARCA4 (SWI/SNF related BAF chromatin remodeling complex subunit ATPase 4). [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 Smarca4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
